Anomalies in the thermal conductivity of honeycomb antiferromagnet MnPS

Jian Yan, Hiromu Okamoto, Hiroki Yoshida +5

Intrinsic two-dimensional magnets serve as a good platform to explore collective, charge-neutral and low-energy excitations. Distinguishing the crucial role of them in experimental…

Field-Angle Dependence of Phonon Thermal Hall Effect in Na2X2TeO6 (X = Co, Zn)

Jian Yan, Hikaru Takeda, Haruka Iwahata +5

The mechanism behind thermal Hall effects by phonons, which are observed in various materials, is not clarified despite the dominant contribution as heat carriers. Theoretically, m…

Observation of Anomalous Thermal Hall Effect in a Kagome Superconductor

Hiroki Yoshida, Hikaru Takeda, Jian Yan +8

Broken time-reversal symmetry (TRS) in superconductors can induce not only spontaneous magnetization by the finite angular momentum of Cooper pairs, but also anomalous thermal Hall…

Magnetic structure of polar magnet GaVSe with Néel-type skyrmion lattice probed by V NMR

Hikaru Takeda, Misaki Ishikawa, Masashi Takigawa +3

We report the magnetization and the V NMR measurements in the polar magnet GaVSe in which a magnetic skyrmion lattice appears in the structural domain with the polar…
