Slow oxidation of magnetite nanoparticles elucidates the limits of the Verwey transition
Taehun Kim, Sangwoo Sim, Sumin Lim +8
Magnetite (Fe3O4) is of fundamental importance as the original magnetic material and also for the Verwey transition near T_V = 125 K, below which a complex lattice distortion and e…
Spin texture induced by non-magnetic doping and spin dynamics in 2D triangular lattice antiferromagnet h-Y(Mn,Al)O3
Pyeongjae Park, Kisoo Park, Joosung Oh +14
Novel effects induced by nonmagnetic impurities in frustrated magnets and quantum spin liquid represent a highly nontrivial and interesting problem. A theoretical proposal of exten…
Pressure-induced transition from Jeff=1/2 to S=1/2 states in CuAl2O4
Hwanbeom Cho, Choong H. Kim, Yongmoon Lee +12
The spin-orbit entangled (SOE) Jeff-state has been a fertile ground to study novel quantum phenomena. Contrary to the conventional weakly correlated Jeff=1/2 state of 4d and 5d tra…
Spin-orbit coupling effects on spin-phonon coupling in Cd2Os2O7
Taehun Kim, Choong H. Kim, Jaehong Jeong +8
Spin-orbit coupling (SOC) is essential in understanding the properties of 5d transition metal compounds, whose SOC value is large and almost comparable to other key parameters. Ove…
Momentum-dependent magnon lifetime in the metallic non-collinear triangular antiferromagnet CrB2
Pyeongjae Park, Kisoo Park, Taehun Kim +8
Non-collinear magnetic order arises for various reasons in several magnetic systems and exhibits interesting spin dynamics. Despite its ubiquitous presence, little is known of how…
Constraining the gravitational coupling of axion dark matter at LIGO
Sunghoon Jung, TaeHun Kim, Jiro Soda +1
The axion-gravity Chern-Simons coupling is well motivated but is relatively weakly constrained, partly due to difficult measurements of gravity. We study the sensitivity of LIGO me…
