Sažetak
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 a SQUID magnetometer and an AC susceptometer. Temperature dependence of magnetization showed existence of antiferromagnetic transition at 10.2K which changes to ferromagnetic transition with application of moderate magnetic field. Hysteresis loops showed ferromagnetic behavior for T<TN and existence of anisotropy. We have seen no effect of electric field on magnetic behavior at low temperatures, but near structural transition temperatures an anomaly of magnetization was observed possibly because of indirect magnetoelectric effect. Results of AC measurements showed no frequency dependence of susceptibility. Obtained temperature dependence of nonlinear susceptibility can be interpreted as a result of successive crossovers between different regimes. This kind of material is interesting because, depending on the organic ion that separates magnetic layers, the spacing between them changes therefore changing the magnetic and electric properties of the compound. Further studies are being made on such compounds with different organic ions.
