Canted ferromagnetic order in a distorted triangular-lattice magnet NaSrCo(VO)
Tengfei Peng, Xiaobai Ma, Xinyang Liu +5
Triangular-lattice cobaltates with glaserite-type Co(O structure provide an ideal platform to investigate intriguing quantum magnetism. Here we report a comprehensi…
Universal Magnetocaloric Effect near Quantum Critical Point of Magnon Bose-Einstein Condensation
Junsen Xiang, Enze Lv, Qinxin Shen +19
Bose-Einstein condensation (BEC), a macroscopic quantum phenomenon arising from phase coherence and bosonic statistics, has been realized in quantum magnets. Here, we report the ob…
Giant Magnetocaloric Effect in Spin Supersolid Candidate NaBaCo(PO)
Junsen Xiang, Chuandi Zhang, Yuan Gao +16
Supersolid, an exotic quantum state of matter that consists of particles forming an incompressible solid structure while simultaneously showing superfluidity of zero viscosity [1],…
Double Magnon-Roton Excitations in the Triangular-Lattice Spin Supersolid
Yuan Gao, Chuandi Zhang, Junsen Xiang +6
Supersolid is an exotic quantum state of matter that spontaneously hosts the features of both solid and superfluid, which breaks the translation and U(1) gauge symmetries. Here we…
Successive magnetic transitions in the spin-5/2 easy-axis triangular-lattice antiferromagnet NaBaMn(PO): A neutron diffraction study
Chuandi Zhang, Junsen Xiang, Cheng Su +7
Motivated by the recent observations of various exotic quantum states in the equilateral triangular-lattice phosphates NaBaCo(PO) with = 1/2 and NaBaNi…
