Abstract
The nonstoichiometric compound Pdx.Coy,O2 (x = 0.72,y = 0.68) were carefully prepared by the metathetical reaction and characterized by the measurements of the powder X-ray diffraction, the inductively coupled plasma spectrum, the DC magnetic susceptibility, and the specific heat. The stoichiometric PdCoO2 exhibits Pauliparamagnetism, while two magnetic phase transitions were indeed observed in Pd0.72Co0.68O2. The deviation of fieldcooled from zero-field-cooled curves appears below 55 K, indicating a certain kind of antiferromagnetic phase transition. The well-defined cusp is seen with a peak at Tg = 4.5 K, indicating the existence of spin-glass like transition.
