Magnetic ground state and electron doping tuning of Curie temperature in FeGeTe: first-principles studies
Zhen-Xiong Shen, Xiangyan Bo, Kun Cao +2
Intrinsic magnetic van der Waals (vdW) materials have attracted much attention, especially FeGeTe (FGT), which exhibits highly tunable properties. However, despite vast…
Ab initio calculation of spin fluctuation spectra using time dependent density functional perturbation theory, planewaves, and pseudopotentials
Kun Cao, Henry Lambert, Paolo G. Radaelli +1
We present an implementation of time-dependent density functional perturbation theory for spin fluctuations, based on planewaves and pseudopotentials. We compute the dynamic spin s…
First-principles study of structurally modulated multiferroic CaMnO
Kun Cao, Roger D. Johnson, Natasha Perks +2
We study the electronic and magnetic structures of multiferroic CaMnO by first-principle calculations, based on the experimentally determined modulated crystal structure…
First-principles study of multiferroic RbFe(MoO)
Kun Cao, R. D. Johnson, Feliciano Giustino +3
We have investigated the magnetic structure and ferroelectricity in RbFe(MoO) via first-principles calculations. Phenomenological analyses have shown that ferroelectricity…
MnSb2O6: A polar magnet with a chiral crystal structure
R. D. Johnson, K. Cao, L. C. Chapon +7
Structural and magnetic chiralities are found to coexist in a small group of materials in which they produce intriguing phenomenologies such as the recently discovered skyrmion pha…
Origin of ferroelectricity in high- magnetic ferroelectric CuO
Guangxi Jin, Kun Cao, Guang-Can Guo +1
Cupric oxide is a unique magnetic ferroelectric material with a transition temperature significantly higher than the boiling point of liquid nitrogen. However, the mechanism of hig…
