Abstract

Magnetic properties in Na_0.75CoO₂ (space group P6₃/mmc) are investigated by DC magnetic measurements from 2 to 300 K. The temperature-dependent magnetic susceptibility data show Curie-Weiss behaviour down to 15 K. Spin glass like characteristics are also found; the cusp anomaly seen at 3 K, irreverisbility between zero-field and field cooled magnetic susceptibility below 13 K.
