The magnetic characteristics of a twin-free EuBaCo2O5.5 single crystal were studied. It is shown that. Co ions exhibit an Ising-type behavior with an easy axis directed along the a axis in the temperature range from 2 K to T, (250 K). As the temperature decreases from 300 K, a number of magnetic phase transitions occur occur under magnetic fields H || a. In the range where anti Ferromagnetic ordering of Co-ions exists, metamagnetic transitions were observed to occur in fields whose values were dependent on temperature. The strengths of competing, interactions in the crystal are estimated.
