Cu(HCOO)(OH) exhibits a strong ferromagnetic interaction ( θ =+43K). The susceptibility shows a sharp maximum at Tm=21K and a plateau below 12K. This magnetic behavior is characteristic of antiferromagnetic materials. The spin-flop behavior is observed below Tm. To examine the spin-flop behavior of Cu(HCOO)(OH), magnetic phase diagram was drawn up. Magnetic phase diagram of Cu(DCOO)(OD) was also constructed to examine whether magnetic interaction between layers is due to hydrogen bond or not. Between them there is little difference in the phase diagram, but there is a remarkable difference in the hysteresis curves at 2K. Besides, temperature dependence of susceptibility and hysteresis curve at 1.8K of Cu3(HCOO)2(OH)4 was measured. In consequence it was found that this material also showed spin-flop behavior.
