Doping effects on the valence bond solid of LiRuO with Mn substitution
Seokhwan Yun, Ki Hoon Lee, Chaebin Kim +5
with a honeycomb structure undergoes a drastic transition from a regular honeycomb lattice with the space group to a valence bond solid state of the $P2_{1}/…
Magnetic and electrical anisotropy with correlation and orbital effects in dimerized honeycomb ruthenate LiRuO
Seokhwan Yun, Ki Hoon Lee, Se Young Park +6
Li2RuO3 undergoes a structural transition at a relatively high temperature of 550 K with a distinct dimerization of Ru-Ru bonds on the otherwise isotropic honeycomb lattice. It exh…
Robust singlet dimers with fragile ordering in two-dimensional honeycomb lattice of LiRuO
Junghwan Park, Teck-Yee Tan, D. T. Adroja +14
When an electronic system has strong correlations and a large spin-orbit interaction, it often exhibits a plethora of mutually competing quantum phases. How a particular quantum gr…
Experimental percolation studies of two-dimensional honeycomb lattice: Li2Mn1-xTixO3
Sanghyun Lee, Junghwan Park, Jiyeon Kim +3
Li2MnO3 with a S=3/2 two-dimensional Mn honeycomb lattice has a Neel-type antiferromagnetic transition at TN=36 K with a broad maximum in the magnetic susceptibility at TM=48 K. We…
Negative magnetostrictive magnetoelectric coupling of BiFeO3
Sanghyun Lee, M. T. Fernandez-Diaz, H. Kimura +8
How the magnetoelectric coupling actually occurs on a microscopic level in multiferroic BiFeO3 is not well known. By using the high-resolution single crystal neutron diffraction te…
Photoemission Study of Rare-Earth Ditelluride Compounds (ReTe_2 : Re = La, Pr, Sm, and Gd)
Jaegwan Chung, Junghwan Park, J. G. Park +5
We studied the electronic structure of rare-earth ditelluride (ReTe_2 : Re = La, Pr, Sm, and Gd) using photoemission spectroscopy. From the x-ray photoelectron spectroscopy (XPS) s…
