Extraordinary electron systems can be generated at well-defined interfaces between
complex oxides. In recent years, progress has been achieved in exploring and making use …

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 …

Magnetic frustrated materials are of great interest for their novel spin-dependent transport
properties. We report an anisotropic anomalous Hall effect in the triangular itinerant …

Colossal magnetoresistance—a huge decrease in resistance in response to a magnetic field—
has recently been observed in manganese oxides with perovskite structure. This effect is …

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 …

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

Half-metallic materials are characterized by the coexistence of metallic behaviour for one
electron spin and insulating behaviour for the other. Thus, the electronic density of states is …

Some of the most relevant finite-size and surface effects in the magnetic and transport
properties of magnetic fine particles and granular solids are reviewed. The stability of the …

The manganese oxides of general formula RE 1− x M x MnO 3 (RE= rare earth, M= Ca, Sr,
Ba, Pb) have remarkable interrelated structural, magnetic and transport properties induced …

The existence of a magnetodielectric (magnetocapacitance) effect is often used as a test for
multiferroic behavior in new material systems. However, strong magnetodielectric effects can …
