Magnetic behaviour of (C2H5NH3)2CuCl4 type multiferroic
Metal organic compound (C2H5NH3)2CuCl4 belongs to the family of layered perovskite multiferroic materials. It consists of ferromagnetic layers of corner sharing [CuCl4] 2− octahedra connected by organic ions (two layers of [C2H5NH3] +). In this work we have studied magnetic properties of (C2H5NH3)2CuCl4 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.
