Thermal Hall Effect of Spins in a Paramagnet

Hyunyong Lee, Jung Hoon Han, Patrick A. Lee

Theory of Hall transport of spins in a correlated paramagnetic phase is developed. By identifying the thermal Hall current operator in the spin language, which turns out to equal t…

Successive spin-flop transitions of Neel-type antiferromagnet LiMnO single crystal with honeycomb-lattice

K. Balamurugan, Sang-Hyun Lee, Jun-Sung Kim +7

We have carried out high magnetic field studies of single-crystalline LiMnO, a honeycomb lattice antiferromagnet. Its magnetic phase diagram was mapped out using magnetizat…

Thermopower enhancement by fractional layer control in 2D oxide superlattices

Woo Seok Choi, Hiromichi Ohta, Ho Nyung Lee

We have investigated two-dimensional thermoelectric properties in transition metal oxide heterostructures. In particular, we adopted an unprecedented approach to direct tuning of t…

Zero-energy Bound States in Nodal Topological Lattice

Soo-Yong Lee, Jung Hoon Han

Nodal topological lattice is a form of magnetic crystal with topologically non-trivial spin texture, which further exhibits a periodic array of nodes with vanishing magnetization.…

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…
