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 …

Electron spin polarization (ESP) refers to the alignment of electron spins in a specified
direction, with burgeoning research underscoring its pivotal role in enhancing rechargeable …

Transition metal oxide catalysts with high oxygen reduction activity and durability are highly
desirable for use in fuel cells and metal-air batteries. Herein we report, for the first time, the …

We study theoretically the thermopower in cobalt oxides generalizing the Heikes formula. In
the oxides, states of carriers are largely degenerate because the crystalline field and Hund's …

Simultaneously engineering the eg electron filling and increasing the intrinsic conductivity is
the bottleneck problem in improving the oxygen electrocatalysis of LaCoO 3-based …

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 …

Transition metal oxides are promising candidates for the next generation of spintronic
devices due to their fascinating properties that can be effectively engineered by strain …

Abstract Lanthanum-based LaMO 3 (M= Fe, Co, Ni) perovskite nanofibers were effectively
fabricated by electrospinning approach coupled with calcination process. The crystallinity …

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 …

To investigate the electronic structure of the electrochemically Li-ion deintercalated Li1-x
CoO2 system, soft X-ray absorption spectroscopy (XAS) for the oxygen K-edge and the Co …
