Field-orientation dependence of quantum phase transitions in the S=1/2 triangular-lattice antiferromagnet BaCoSbO
Kazuki Okada, Hidekazu Tanaka, Nobuyuki Kurita +3
BaCoSbO approximates the two-dimensional spin-1/2 triangular-lattice Heisenberg antiferromagnet. This compound displays magnetic-field-induced quantum phase transitions…
Contrasting Magnetic Structures in SrLaCuSbO and SrLaCuNbO: Spin-1/2 Quasi-Square-Lattice Heisenberg Antiferromagnets
Masari Watanabe, Nobuyuki Kurita, Hidekazu Tanaka +4
We report the magnetic properties of the double perovskites SrLaCuSbO (SLCSO) and SrLaCuNbO (SLCNO). The temperature dependence of the magnetic susceptibilities of both com…
Possible Intermediate Quantum Spin Liquid Phase in -RuCl under High Magnetic Fields up to 100 T
Xu-Guang Zhou, Han Li, Yasuhiro H. Matsuda +6
Pursuing the exotic quantum spin liquid (QSL) state in the Kitaev material -RuCl has intrigued great research interest recently. A fascinating question is on the possible ex…
