$J_1-J_2$ Square-Lattice Heisenberg Antiferromagnets with 4$d^1$ spins: AMoOPO${}_4$Cl (A = K, Rb)

Hajime Ishikawa, Nanako Nakamura, Makoto Yoshida +6

Magnetic properties of AMoOPO${}_4$Cl (A = K, Rb) with Mo${}^{5+}$ ions in the 4$d^1$ electronic configuration are investigated by magnetization, heat capacity and NMR measurements on…
