Magnetic Dimensionality of Metal Formate $M[(H_2O)_2 (HCOO)_2]$ Compounds ($M={}$Co(II), Cu(II))

Magnetic ordering in dihydrated formates M(HCOO)2 · 2H2O, M = Mn, Fe, Co, Ni: DC magnetization study

“…The cobalt formate dihydrate system has been studied and a two‐dimensional antiferromagnetic transition with T N = 5.2 K has been detected. The exchange interactions in the A plane and between the A and B planes were shown to be antiferro‐ and ferromagnetic, respectively .…”
