Multiferroic materials, which combine ferroelectric and ferromagnetic properties, are promising candidates for novel nanoscale switching and memory devices, especially if there is a coupling between those properties. Here, we present low-temperature noncontact atomic force microscopy (nc-AFM) - in particular magnetic force microscopy (MFM) and Kelvin probe force microscopy (KPFM) - investigations of multiferroic BiCrO3 and BiFeO3 thin films prepared by pulsed laser deposition (PLD) as described in [1]. In addition to the nc-AFM investigations, piezoresponse force microscopy (PFM) was used to study the ferroelectric switching behaviour of the thin films. Although the separation of magnetic and ferroelectric properties is nontrivial due to the long range nature of both of the related forces, we were able to clearly separate the two different domain types by simultaneously running KPFM and MFM.

Magnetic Resonance Force Microscopy in Anisotropic Systems Thomas Fan and Vladimir I. Tsifrinovich 1 1 Department of Physics, Polytechnic Institute of NYU, Brooklyn, USA 161 P.II-33 We have developed theory for the detection of a single spin S≥1 using magnetic resonance force microscopy (MRFM), a subset of atomic force microscopy. The anisotropy caused by the crystalline field is taken into account. The MRFM signal (i.e. the frequency shift of the cantilever vibrations) in the oscillating cantilever-driven adiabatic reversals technique is computed using a semi-classical approach: the spin is treated quantum mechanically, and the cantilever vibrations classically. We have shown that the MRFM signal for spin S≥1 is the same as for the spin S=1/2. We have obtained the analytical estimate for the half-width of the MRFM signal.
