説明
The fully mapped T-H (temperature-magnetic field) phase diagram of a quasi-two-dimensional (2d) antiferromagnet Mn(HCOO)2·2H2O (TN=3.69 K) has been determined by the measurements of magnetic heat capacity and susceptibility. The critical field has been estimated to be 105±5 kOe at T=0 K, which gives the intra-layer exchange constant |J|⁄kB=0.35±0.02 K. By applying external field, an anomalous increase of the Néel temperature TN(H) has been found (TN(H)≈1.10TN(0) at H=35 kOe) for the first time in this 2d compound as in the case of quasi-1d compounds.
