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 …

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

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 …

Perovskite nickelates (RNiO3, where R is rare earth or a heavy metal such as Tl or Bi)
display sharp metal–insulator transitions, unusual magnetic order, charge order and …

The first direct observation of charge order of Ni 3+ δ′ and Ni 3− δ by resonant x-ray
scattering experiments in an epitaxial film of NdNiO 3 is reported. A quantitative value of δ+ …

We present a study of the crystallography and transport properties of NdNiO 3 thin films,
grown by pulsed-laser deposition, on a variety of substrates and with a range of thicknesses …

Protonation can be used to tune diverse physical and chemical properties of functional
oxides. Although protonation of nickelate perovskites has been reported, details on the …

The structural and electrical transport properties of LaMn 1− x Fe x O 3 (0.1≤ x≤ 0.6) bulk
samples have been investigated. The powder x-ray diffraction patterns at room temperature …

The interdependences of different phase transitions in Mott materials are fundamental to the
understanding of the mechanisms behind them. One of the most important relations is …

Nickelates are known for their metal to insulator transition (MIT) and an unusual magnetic
ordering, occurring at T= T Néel. Here, we investigate thin films of SmNiO 3 subjected to …
