We report a detailed single crystal investigation of a magnetoelectricferrimagnet Cu2OSeO3 using dc magnetization and ac susceptibility along thethree principal directions [100], [110] and [111]. We have observed that insmall magnetic fields two magnetic transitions occur, one at Tc = 57 K and thesecond one at TN = 58 K. At Tc the non-linear susceptibility reveals theemergence of the ferromagnetic component and below Tc the magnetizationmeasurements show the splitting between field-cooled and zero-field-cooledregimes. Above 1000 Oe the magnetization saturates and the system is in asingle domain state. The temperature dependence of the saturation below Tc canbe well described by m(T) = m(0)[1 - (T/Tc)^2]^{\beta}, with m(0) = 0.56(mu)B/Cu, corresponding to the 3-up-1-down configuration. The dielectricconstant measured on a thin single crystal shows a systematic deviation belowthe transition, indicating an intrinsic magnetoelectric effect.
