Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …

An electron in a solid, that is, bound to or nearly localized on the specific atomic site, has
three attributes: charge, spin, and orbital. The orbital represents the shape of the electron …

The magnetocaloric effect describes the change in temperature of a magnetic material under
adiabatic conditions through the application or removal of an external magnetic field. This …

Mixed-valence manganese oxides (R1-χAχ) MnO3 (R= rare-earth cation, A= alkali or
alkaline earth cation), with a structure similar to that of perovskite CaTiO3, exhibit a rich …

The fundamental physical properties of doped LaMnO 3, generically termed “manganites,”
and much of the underlying physics, were known more than 40 years ago. This article first …

We review recent experimental work falling under the broad classification of colossal
magnetoresistance (CMR), which is magnetoresistance associated with a ferromagnetic-to …

Magnetoelectronic features of the perovskite-type manganites are overviewed in the light of
the mechanism of the colossal magnetoresistance (CMR). The essential ingredient of the …

The features and mechanism of Colossal Magnetoresistance, or CMR, in manganese oxides
as well as device physics are highlighted in this book, with a focus on tunneling MR for some …

Room temperature magnetic refrigeration is a new highly efficient and environmentally
protective technology. Although it has not been maturely developed, it shows great …

The perovskite manganites with generic formula RE 1− x AE x MnO 3 (RE= rare earth, AE=
Ca, Sr, Ba and Pb) have drawn considerable attention, especially following the discovery of …
