Orbital-selective confinement effect of Ru orbitals in SrRuO ultrathin film
Soonmin Kang, Yi Tseng, Beom Hyun Kim +11
The electronic structure of SrRuO thin film with thickness from 50 to 1 unit cell (u.c.) is investigated via the resonant inelastic x-ray scattering (RIXS) technique at the O K…
Anisotropic magnetic properties and giant rotating magnetocaloric effect in double-perovskite Tb2CoMnO6
J. Y. Moon, M. K. Kim, D. G. Oh +4
We investigated the anisotropy of the magnetic and magnetocaloric properties of singlecrystalline double perovskite Tb2CoMnO6, which crystallizes in a monoclinic P21/n structure. D…
Magnetic Excitations in Non-Collinear Antiferromagnetic Weyl Semimetal
Pyeongjae Park, Joosung Oh, Klára Uhlířová +10
has recently attracted considerable attention as a magnetic Weyl semimetal exhibiting concomitant transport anomalies at room temperature. The topology of the e…
Theoretical evidence of spin-orbital-entangled =1/2 state in the 3 transition metal oxide CuAlO
Choong H. Kim, Hwanbeom Cho, Santu Baidya +6
Transition metal oxides exhibit various competing phases and exotic phenomena depending on how their reaction to the rich degeneracy of the -orbital. Large spin-orbit coupling (…
Stable hump-like Hall effect and non-coplanar spin textures in SrRuO ultrathin film
Byungmin Sohn, Bongju Kim, Se Young Park +11
We observed a hump-like feature in Hall effects of SrRuO ultrathin films, and systematically investigated it with controlling thicknesses, temperatures and magnetic fields. The…
Hybridization and Decay of Magnetic Excitations in two-dimensional Triangular Lattice Antiferromagnets
Taehun Kim, Kisoo Park, Jonathan C. Leiner +1
Elementary quasiparticles in solids such as phonons and magnons occasionally have nontrivial interactions between them, as well as among themselves. As a result, their energy eigen…
