Hund's physics and the magnetic ground state of CrOX (X = Cl, Br)
Seung Woo Jang, Do Hoon Kiem, Juhyeok Lee +3
To understand the magnetic property of layered van der Waals materials CrOX (X = Cl, Br), we performed the detailed first-principles calculations for both bulk and monolayer. We fo…
On the origin and the manipulation of ferromagnetism in FeGeTe: defects and dopings
Seung Woo Jang, Min Yong Jeong, Hongkee Yoon +2
To understand the magnetic properties of FeGeTe, we performed the detailed first-principles study. Contrary to the conventional wisdom, it is unambiguously shown that Fe$_3…
Magnetic force theory combined with quasi-particle self-consistent GW method
Hongkee Yoon, Seung Woo Jang, Jae-Hoon Sim +2
We report a successful combination of magnetic force linear response theory with quasiparticle self-consistent GW method. The self-consistently determined wavefunctions and eigenva…
Anomalous behavior of the quasi-one-dimensional quantum material NaOsO at high pressure
Raimundas Sereika, Kazunari Yamaura, Yating Jia +10
NaOsO is an unusual quantum material that, in contrast to the common 5 oxides with spins = 1, owns a magnetically silent ground state with spin = 0 and a band…
Microscopic understanding of magnetic interactions in bilayer CrI
Seung Woo Jang, Min Yong Jeong, Hongkee Yoon +2
We performed the detailed microscopic analysis of the inter-layer magnetic couplings for bilayer CrI. As the first step toward understanding the recent experimental observation…
Calculating magnetic interactions in organic electrides
Taek Jung Kim, Hongkee Yoon, Myung Joon Han
We present our calculation results for organic magnetic electrides. In order to identify the `cavity' electrons, we use maximally-localized Wannier functions and `empty atom' techn…
