S Y S T E MF E A T U R E STHE QUANTUM DESIGN PHYSICAL PROPERTYEASE OF USEMEASUREMENT SYSTEM (PPMS) REPRESENTSA UNIQUE CONCEPT IN LABORATORYEQUIPMENT. IT IS AN OPEN ARCHITECTURE,VARIABLE TEMPERATURE-FIELD SYSTEMTHAT IS OPTIMIZED TO PERFORM A VARIETYOF AUTOMATED MEASUREMENTS. ATQUANTUM DESIGN WE KNOW YOUR TIME ISVALUABLE, SO WE BROUGHT LABORATORYThe hallmarks of the PPMS areautomation and ease of use. Youcan quickly and easily configure thePPMS to perform different types ofmeasurements. In a matter of minutesyou can install a measurement application,set up an automated sequence,and start collecting meaningful data.And, the PPMS is designed to run24 hours a day, 7 days a week.AUTOMATION TO A NEW LEVEL. WHILE THEPPMS AUTOMATICALLY RUNS YOUR MEASURE-MENTS, YOU CAN BE ANALYZING DATA FROMPREVIOUS MEASUREMENTS, PLANNING YOURNEXT EXPERIMENT, AND CREATING NEWMATERIALS.THE PPMS WORKS LIKE A DEDICATEDSYSTEM, BUT ITS TREMENDOUS FLEXIBILITYLETS YOU PERFORM DIFFERENT TYPES OFPPMS MULTIVU SOFTWAREPPMS MultiVu is Windows -basedcontrol software that contains all thefunctions essential for each measurementapplication. With it you cancreate measurement sequences thatautomate system operation, and youcan control system parameters, suchas magnetic field and temperature,manually. Plus, you can review saveddata and monitor data as the PPMScollects it. All systems come completewith remote capability.MEASUREMENTS.

MAGNETOMETRYBECAUSE MAGNETOMETRY APPLICATIONSARE USED IN CONJUNCTION WITH THEAUTOMATED TEMPERATURE AND FIELDCONTROL CAPABILITY OF THE PPMS, THERESULT IS A POWERFUL, FULLY AUTOMATEDMAGNETIC MEASUREMENT WORKSTATIONTHAT INLCUDES INTEGRATED SOFTWARE.AC/DC MAGNETIZATIONThe AC Measurement System(ACMS) provides you with the capabilityto perform both AC susceptibilityand extraction DC magnetizationmeasurements without changinghardware.FEATURES:A single automated measurementsequence can perform both AC andDC magnetization measurements.Direct measurement of the instrumentalphase shift, not available onany other AC susceptometer: Thisfeature uses integrated, low inductancecalibration coils to measureand subtract background phaseshifts prior to every AC measurementpoint.Pictured are theservo-motor, coilset, and sample rodfor the ACMS.High-speed digital filtering: Byusing a DSP chip, the ACMSimproves the signal-to-noise ratioover analog filters to offer excellentperformance over a wide frequencyrange.A compensation coil reducesenvironmental noise in ACsusceptibility measurements.SPECIFICATIONS:Temperature Range: 1.9-350 KAC Frequency Range: 10 Hz to10 kHzAC Field Amplitude Range: 2 mOeto 15 OeSensitivity Range: DC magnetizationmeasurements: 2.5 x 10 -5 emuto 5 emu (2.5 x 10 -8 Am 2 to 5 x10 -3 Am 2 )AC Susceptibility Measurements:2 x 10 -8 emu (2 x 10 -11 Am 2 @10 kHz)The ACMS cannot be used with the 7-TTransverse & 16T systems. Performanceis reduced in the 14-T system due tolower field homogeneity. Temperaturestability may be reduced at low temperaturesdue to sample movement.ULTRA LOW FIELD†The Ultra Low Field (ULF) capabilityis also available on the PPMS andprovides fully automated remanentfield profiling and nulling. Using afluxgate magnetometer, a superconductinglow-field magnet coil, magnet-resetheater, and the ACMS hardware,the ULF option actively nullsthe remanent field so you may performzero-field cooled measurements.Tq-Mag chip with integrated Wheatstonebridge.TORQUE MAGENTOMETRY*The Torque Magnetometer (Tq-Mag)is specifically designed to measuresmall, anisotropic samples, such assingle crystals and thin films. It performsfully automated, high-sensitivity,angular-dependent measurements ofmagnetic torque over the full rangeof magnetic fields and temperatures.SPECIFICATIONS:Sample Size: Up to 2 x 2 mm 2RMS Torque Noise Level: 1 x 10 -9 Nmfor 40 sec. sampling time* Quantum Design developed the Torque Magnetometerin collaboration with the IBM Research Division, ZŸrichResearch Laboratory, and the Physik-Institutder UniversitŠt ZŸrich, Switzerland.SPECIFICATIONS:Residual Field: < 0.1 Oe at any pointResidual Field Uniformity: < ±0.1 Oealong 4 cm at the center of thecoil set† Not available for the 7-T Transverse, 14-T, or16-T systems.41070-002 Rev.

These platformshold the sample parallel or perpendicularto the field. Vertical Rotator is pictured.DESIGN. LET QUANTUM DESIGN SIMPLIFYYOUR TRANSPORT MEASUREMENTS.AC TRANSPORTMEASUREMENT SYSTEMThe AC Transport measurementsystem (ACT) option is a precisioncurrent source and voltage detectorthat supports four different types ofautomated, electrical transport measurements:AC resistivity, five-wireHall effect, I-V curve, and criticalcurrent. A PPMS integrated withACT provides fast data acquisitionand the convenience of measuringup to two samples on a singlesample mount.SPECIFICATIONS:Current Range: 10 µA to 2 ASensitivity: 1 nV @ 1 kHzFrequency Range: 1 Hz to 1 kHzDC RESISTIVITYThe DC Resistivity option adds resistancebridge capability to the Model6000 PPMS Controller. This bridgeprovides four independent channelsthat you can use for van der Pauwand four-wire resistance measurements(up to three samples in asingle sequence).SPECIFICATIONS:Current Range: 5 nA to 5 mASensitivity: 20 nVHORIZONTAL AND VERTICALROTATORSYou may also take advantage of theHorizontal and Vertical Rotators toobtain information about angulardependence. Samples are mounted onremovable platforms. A thermometer, indirect contact with the platform, accuratelydetermines the sample temperature.Both rotators are available withstandard or high-resolution motors.The Horizontal Rotator option rotatesthe sample about the horizontal axis.SPECIFICATIONS:Range: -10˚ to 370˚Angular Step Size: 0.053˚ for standardresolution; 0.0045˚ for highresolutionThe Vertical Rotator option rotates thesample about the vertical axis.SPECIFICATIONS:Angular Step Size: 0.013˚ for standardresolution; 0.002˚ for highresolutionMULTI-FUNCTION PROBEThe Multi-Function Probe optionextends measurement capabilities of thePPMS by allowing you to easily addhardware such as fiber optics, microwaveguides, and external electricalleads to customize your experiment.This probe incorporates the PPMS samplespace electrical connections and canutilize the electro-transport accessories.51070-002 Rev.
