Seminar in Fujimori-Mizokawa Group
In this talk, recent developments in the context of theory and
experiments for manganites will be discussed. It will be argued that
the presence of nanoscale phase separation is at the heart of the
CMR phenomenon . Simulation results and mean-field approximations
support this view, as well as plenty of experimental information.
These effects are not limited to manganites, but they appear in other
compounds as well, such as the high-Tc cuprates. In addition, related
physics is present in models of diluted magnetic semiconductors
and results will be shown. The overall picture is that ``clustered''
states may be needed as a new paradigm to understand the properties
of many interesting materials.
