(color online) (a) The crystal structure of the compound MA₂CuCl₄. (b) The temperature dependences of magnetization for MA₂CuCl₄ in zero-field-cooling (ZFC) at applied magnetic fields of 5, 10, 25, 100, 200 Oe and field-cooling (FC) at magnetic fields of 5, 10 Oe. The red dashed line indicates the Curie temperature T_c determined by the inflection point of low-field M–T curve.
