✦ Synopsis

For insulating Eu A MnO A s Ca, Sr; x s 0, 0.3 ceramics the magnetic properties depend on the 1yx

x 3 thermomagnetic history of the sample and the maximum of initial magnetic susceptibility is located at T s T , being N independent of the AC field frequency. Magnetization isotherms are the superposition of the linear part and spontaneous magnetization. The maximum of electrical resistivity and colossal magnetoresistance are observed in the T region. These N properties are explained by the magnetic two-phase state.
