Electronic structure and phase transition in polar ScFeO3 from First Principles Calculations

Bog G. Kim, M. Toyoda, Janghee Park +1

The properties of newly discovered polar ScFeO3 with magnetic ordering are examined using Ab initio calculations and symmetry mode analysis. The GGA+U calculation confirms the stab…

An Unconventional Phase Transition in BaAl2O4 Driven by Two Competing Soft Modes

Y. Ishii, S. Mori, Y. Nakahira +4

We investigated the temperature dependence of the superlattice intensity and thermal diffuse scattering intensity of BaAl2O4, which has a network structure with corner-sharing AlO4…

Kinetically-controlled thin-film growth of layered $β$ - and $γ -$ Na $_{x}$ CoO $_{2}$ cobaltate

J. Y. Son, Bog G. Kim, J. H. Cho

We report growth characteristics of epitaxial $β$ -Na $_{0.6}$ CoO $_{2}$ and $γ$ -Na $_{0.7}$ CoO $_{2}$ thin films on (001) sapphire substrates grown by pulsed-laser deposition. Reductio…
