Abstract

Two forms of CoO have been prepared from spec. pure Co metal and CoCO3 and the magnetic susceptibility of CoO(I) and CoO(II) examined over a temperature range300-700 deg. K. The magnetic data of CoO(II) have shown an anomalous temperature dependence of that in this temperature range CoO(II) passes into CoO(I). This result is in conformity with Mossbauer spectra. Furthermore, D.T.A and temperature dependence of magnetic susceptibility of CoO(II) arises from a first order phase transition.
