The properties of transition metal compounds are largely determined by nontrivial interplay
of different degrees of freedom: charge, spin, lattice, and also orbital ones. Especially rich …

SrRuO 3 is endowed with three remarkable features. First, it is a moderately correlated
material that exhibits several novel physical properties; second, it permits the epitaxial …

Concomitant with the development of metal-based spintronics in the late 1980s and 1990s,
important advances were made on the growth of high-quality oxide thin films and …

Ionic substitution forms an essential pathway to manipulate the structural phase, carrier
density and crystalline symmetry of materials via ion-electron-lattice coupling, leading to a …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

In correlated metals derived from Mott insulators, the motion of an electron is impeded by
Coulomb repulsion due to other electrons. This phenomenon causes a substantial reduction …

We have revealed the phase diagram of Ca 2− x Sr x RuO 4: the quasi-two-dimensional Mott
transition system that connects the Mott insulator Ca 2 RuO 4 with the spin-triplet …

The crystal and magnetic structure of Ca 2 RuO 4 (CRO) has been studied by powder
neutron diffraction. CRO was synthesized in two different modifications (stoichiometric and …

Increasing demands for high-density, stable nanoscale memory elements, as well as
fundamental discoveries in the field of spintronics, have led to renewed interest in exploring …

Since the discovery of perovskite materials with the general chemical formula ABX3 in 1839,
research on perovskite materials has drawn exponentially greater attention, owing to their …
