Critical Berezinskii-Kosterlitz-Thouless dynamics in the archetypal two-dimensional spin system BaCuSiOCl
K. M. Ranjith, Maxime Dupont, Steffen Krämer +6
We study the spin dynamics in the quasi-2D spin- dimer compound BaCuSiOCl, which exhibits a magnetic field-induced Bose-Einstein condensate (BEC) of triplons.…
NiCrAl piston-cylinder cell for magnetic susceptibility measurements under high pressures in pulsed high magnetic fields
Katsuki Nihongi, Takanori Kida, Yasuo Narumi +5
We developed a metallic pressure cell made of nickel-chromium-aluminum (NiCrAl) for use with a non-destructive pulse magnet and a magnetic susceptibility measurement apparatus with…
Particle-hole symmetry breaking in a spin-dimer system TlCuCl observed at 100 T
X. -G. Zhou, Yuan Yao, Y. H. Matsuda +4
The entire magnetization process of TlCuCl has been experimentally investigated up to 100 T employing the single-turn technique. The upper critical field is observed t…
Sample dependence of the half-integer quantized thermal Hall effect in the Kitaev candidate -RuCl
M. Yamashita, J. Gouchi, Y. Uwatoko +2
We have investigated the sample dependence of the half-integer thermal Hall effect in -RuCl under a magnetic field tilted 45 degree from the axis to the axis. We fin…
Half-integer quantized anomalous thermal Hall effect in the Kitaev material -RuCl
T. Yokoi, S. Ma, Y. Kasahara +9
Heat transport mediated by Majorana edge modes in a magnetic insulator leads to a half-integer thermal quantum Hall conductance, which has recently been reported for the two-dimens…
Evidence of one-dimensional magnetic heat transport in the triangular-lattice antiferromagnet CsCuCl
E. Schulze, S. Arsenijevic, L. Opherden +5
We report on low-temperature heat-transport properties of the spin-1/2 triangular-lattice antiferromagnet CsCuCl. Broad maxima in the thermal conductivity along the three p…
Pressure-tuning the quantum spin Hamiltonian of the triangular lattice antiferromagnet CsCuCl
S. A. Zvyagin, D. Graf, T. Sakurai +6
Quantum triangular-lattice antiferromagnets are important prototype systems to investigate phenomena of the geometrical frustration in condensed matter. Apart from highly unusual m…
Microscopic properties of the "pinwheel" kagome compound Rb_2Cu_3SnF_{12}
M. S. Grbić, S. Krämer, C. Berthier +4
Using Cu nuclear magnetic resonance (NMR) in magnetic fields up to 30 T we study the microscopic properties of the 12-site valence-bond-solid ground state in the "pinwhee…
Partial ferromagnetic ordering and indirect exchange interaction in spatially anisotropic kagome antiferromagnet Cs_2Cu_3CeF_{12}
T. Amemiya, M. Yano, K. Morita +5
We report the crystal structure and unconventional magnetic ordering of Cs_2Cu_3CeF_{12}, which is composed of buckled kagome lattice of Cu^{2+} ions. The exchange network in the b…
Magentic Ordering under Hydrostatic Pressure in Doped Spin Gap Systems ACuMgCl: ATl and K
T. Ono, H. Imamura, J. Kawakami +2
Magnetic phase transitions under hydrostatic pressures in spin gap systems TlCuMgCl and KCuMgCl were investigated by magnetization m…
Field-Induced Two-Step Phase Transitions in the Singlet Ground State Triangular Antiferromagnet CsFeBr
Y. Tanaka, H. Tanaka, T. Ono +7
The ground state of the stacked triangular antiferromagnet CsFeBr is a spin singlet due to the large single ion anisotropy . The field-induced magnetic ordering in th…
CsMn(Br_xI_{1-x})_3: Crossover from an XY to an Ising Chiral Antiferromagnet
