Investigating electronic structure and excitations under extreme conditions gives access to a
rich variety of phenomena. High pressure typically induces behavior such as magnetic …

Complex cobalt oxides known as cobaltites are reviewed, including LnCoO 3-based
perovskite-structured rare-earth cobaltites (where Ln is lanthanum or a lanthanide), quasi …

The perovskites and perovskite-related structures exhibit several features of technical as
well as fundamental interest. Technically useful properties include oxide-ion conduction …

Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co-L 2, 3
edge, we reveal that the spin state transition in LaCoO 3 can be well described by a low-spin …

The structural properties of LaCoO 3 were studied by means of high-resolution neutron
powder diffraction in the temperature range 5<~ T<~ 1000 K. Changes of the Co+ 3 spin …

We present measurements of the magnetic susceptibility and of the thermal expansion of a
LaCoO 3 single crystal. Both quantities show a strongly anomalous temperature …

The crystallographic structure and the magnetic order of the distorted perovskite La 1− x Sr x
CoO 3 (0.10<~ x<~ 0. 3 0) has been studied by neutron diffraction, high-resolution electron …

High-entropy concept introduced with a promising paradigm to obtain exotic physical
properties has motivated us to explore the thermoelectric properties of Sr-substituted high …

Double-perovskite PrBaCo2/3Fe2/3Cu2/3O5+ δ (PBCFC) is synthesized by the EDTA–
citrate complexing method, and investigated as a novel cathode material for CeO2-based …

A gradual spin-state transition occurs in LaCoO 3 around T∼ 80–120 K, whose detailed
nature remains controversial. We studied this transition by means of inelastic neutron …
