This review stands in the larger framework of functional materials by focussing on
heterostructures of rare-earth nickelates, described by the chemical formula RNiO 3 where R …

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 …

The electronic structure of transition metal oxides featuring correlated electrons can be
rationalized within the Zaanen-Sawatzky-Allen framework. Following a brief description of …

The wide spectrum of exotic properties exhibited by transition-metal oxides stems from the
complex competition between several quantum interactions,. The capacity to select the …

Abstract perovskites (R= rare earth) provide a remarkable opportunity to study the
relationship between structural and physical properties since, by moving along the 4f rare …

In this contribution to the special issue on multiferroics we focus on multiferroicity driven by
different forms of charge ordering. We will present the generic mechanisms by which charge …

Rare-earth nickelates form an intriguing series of correlated perovskite oxides. Apart from
LaNiO3, they exhibit on cooling a sharp metal-insulator electronic phase transition, a …

Over the oxygen composition range 2.5≤ x≤ 3.0, the SrFeOx system exists as four distinct
compounds with the nominal composition SrnFenO3n− 1 (n= 2, 4, 8, and∞). The end …

The evolution of spin-and orbital-ordered states has been investigated for a series of
insulating perovskites R MnO 3 (R= L a, P r, N d,…). R MnO 3 with a large GdFeO 3-type …

Neutron and synchrotron diffraction data provide the first observation of changes in the
crystal symmetry at the metal-insulator transition in R NiO 3 perovskites. At high …
