Magnetic and thermal properties of the nanocomposite compound Gd Ni O 3

This paper discusses the temperature and field dependences of the magnetization of the nanocomposite compound Gd Ni O 3 in the temperature interval 0.5 – 150 K in magnetic fields up to 14 T . The temperature dependences of the heat capacity are also investigated in magnetic fields up to 9 T . Anomalies of the static susceptibility, heat capacity, and dynamic magnetization are detected at temperatures of 0.7, 1.6, and 13 K , respectively. The detected anomalies are associated with magnetic phase transitions.
