| Abstract: | Magnetic susceptibility χ of several CoO samples has been measured in the temperature range of 4.2–350 K. Below about 140 K, and additional contribution to χ, different for different samples, is observed. It is proposed that this excess susceptibility is due to an uncompensated moment resulting from deviations from stoichimetry. The estimated χ values for a stoichiometric CoO at TN and absolute zero agree with Tachiki's calculations. |
