Magnetocaloric effect measurements in ultrahigh magnetic fields up to 120 T
Reon Ogawa, Masaki Gen, Kazuyuki Matsuhira +1
We report proof-of-concept measurements of the magnetocaloric effect (MCE) in ultrahigh magnetic fields up to 120 T for the classical spin-ice compound HoTiO. Rad…
Crystal-field magnetostriction of the spin ice under ultrahigh magnetic fields
Nan Tang, Masaki Gen, Martin Rotter +9
We present a comprehensive study of the magnetoelastic properties of the Ising pyrochlore oxide HoTiO, known as spin ice, by means of high-field magnetostriction…
Anisotropic Optical Conductivity Accompanied by a Small Energy Gap in One-Dimensional Thermoelectric Telluride Ta4SiTe4
Fumiya Matsunaga, Yoshihiko Okamoto, Yasunori Yokoyama +7
We investigated the optical properties of single crystals of one-dimensional telluride Ta4SiTe4, which shows high thermoelectric performance below room temperature. Optical conduct…
Cluster Toroidal Multipoles Formed by Electric-Quadrupole and Magnetic-Octupole Trimers: A Possible Scenario for Hidden Orders in CaIrO
Satoru Hayami, Satoshi Tsutsui, Hiroki Hanate +3
Cluster multipole orderings composed of atomic high-rank multipole moments are theoretically investigated with a 5-electron compound CaIrO in mind. CaIrO$…
Universal dynamics of magnetic monopoles in two-dimensional kagomé ice
Hiroshi Takatsu, Kazuki Goto, Hiromi Otsuka +8
A magnetic monopole in spin ice is a novel quasiparticle excitation in condensed matter physics, and we found that the ac frequency dependent magnetic susceptibility in the…
Ab initio Derivation of Low-Energy Hamiltonians for Systems with Strong Spin-Orbit Interaction and Its Application to Ca5Ir3O12
Maxime Charlebois, Jean-Baptiste Morée, Kazuma Nakamura +7
We present an ab initio derivation method for effective low-energy Hamiltonians of material with strong spin-orbit interactions. The effective Hamiltonian is described in terms of…
