Successive magnetic transitions in the spin-5/2 easy-axis triangular-lattice antiferromagnet Na${}_2$BaMn(PO${}_4$)${}_2$: 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 Na${}_2$BaCo(PO${}_4$)${}_2$ with $J{}_{\mathrm{eff}}$ = 1/2 and Na${}_2$BaNi…
