ALL-IN-ONE SPINTRONICS: MANIPULATING ELECTRONIC PHASE
SEPARATION IN COMPLEX OXIDES

In complex oxides systems such as manganites, electronic phase separation
(EPS), a consequence of strong electronic correlations, dictates the exotic
electrical and magnetic properties of these materials. Investigation of EPS
phenomena is not only important for understanding the strong electronic
correlations in these materials, but also very useful for tuning their physical
properties. Most work in studying EPS has focused on observing EPS and
understanding its formation mechanism. The natural appearance of EPS
domains, as expected, is totally random in terms of their size and spatial
distribution. In order to control the EPS and thus the physical properties of the
complex oxides, in recent years we have developed several methods to control
the shape, density, location, size, spatial distribution and even the very existence
of the EPS domains in manganites. As a result, we are able to order array the
EPS domains and finely tune the corresponding physical properties. It is hoped
that these abilities will allow us to soon design spintronic devices by patterning
EPS domains in one material. These new spintronic devices do not have
chemical interfaces and thus are expected to have high spin transport efficiency.
