The static and dynamic magnetical properties of the perovskite-like complex oxide Nd2/3Ca1/3MnO3, which possesses colossal magnetoresistance effect and is being in the state of the nanoscale structural separation, are studied. Below 130 K, the compound contains clusters of three different magnetic phases and is being magnetic cluster glass. The experimental data obtained, namely strongly divergent ZFC and FC depend-ences of the static magnetizations, frequency dependences of the dynamic magnetization, and the ageing effect, are evidence of the glass behaviour of a system. External magnetic field up to 5 T does not suppress completely the glassy state. Deep minimum at the temperature dependence of the imaginary part of the dynamic magnetization points to the ferromagnetic ordering in the neodymium subsystem.
