Highlights • Possible change of metal ions and organic blocks in layered metal-organic perovskites. • Magnetic anisotropy and transitions from Heisenberg 2D to 3D and to Ising 3D magnet. • Changes of magnetization at temperatures of structural transformations. Abstract Metal organic compound (C 2 H 5 NH 3) 2 CuCl 4 belongs to the family of layered perovskite multiferroic materials. It consists of ferromagnetic layers of corner sharing [CuCl 4 ]2− octahedra connected by organic ions (two layers of [C 2 H 5 NH 3 ]+). In this work we have studied magnetic properties of (C 2 H 5 NH 3) 2 CuCl 4 using SQUID magnetometer and AC susceptometer. Temperature dependence of magnetization showed existence of the antiferromagnetic transition at 10.2 K which changes to ferromagnetic with the application of moderate magnetic field. Near structural transition temperatures the anomaly of magnetization was observed. Hysteresis loops showed ferromagnetic behaviour for T < T N and existence of anisotropy. Results of AC measurements showed no frequency dependence of the susceptibility and obtained temperature dependence of nonlinear susceptibility can be interpreted as a result of successive crossovers between different regimes.
