In the last decade, due to their physical properties, metal-organic layered pervoskites became a subject of many scientific investigations. Metal-organic compounds such as triflourethylammonium tetrabromocuprate (F_3EA)_2CuBr_4 and triflourethylammonium tetrachlorocuprate (F_3EA)_2CuCl_4 belong to a family of layered pervoskite materials that could be potentially multiferroic. They are composed of ferromagnetic octahedric layers, interbedded with double layer of organic cations. In this research, we studied magnetic behaviour of both aforementioned compounds using the SQUID magnetometer. This device is used for observing magnetic properties in small experimental samples through a wide range of temperatures and magnetic fields. We measured temperature dependence of magnetisation M(T) in three different applied external magnetic fields and isothermal field dependence of magnetisation at temperatures 2 K and 20 K. Temperature dependence of magnetisation for (F_3EA)_2CuBr_4 showed existence of ferromagnetic phase transition at Curie temperature of T_C = 12.8 K, while temperature dependence of magnetisation for compound (F_3EA)_2CuCl_4 showed existence of characteristic antiferromagnetic phase transition at T_N = 8.9 K which is a consequence of antiferromagnetic interactions between neighbouring ferromagnetic layers. Measurements of isothermal field dependence of magnetisation are shown through magnetic hysteresis which exhibit ferromagnetic behaviour at temperatures below the phase transition temperature. By doing so, the basic magnetic properties of these novel compounds are characterized.
