摘　　要：Thermomagnetic properties of the new compound Dy6FeSb2 were investigated by vibrating sample magnetometer. The sample of the compound Dy6FeSb2 showed soft magnetic behavior in the investigated temperature range from 85 to 300 K and the ferromagnetic-paramagnetic transition of the compound was a second-order transition. The Landau theory of second-order phase transition was employed to investigate the thermodynamic transition temperature and the specific heat. The calculated transition temperature and the specific heat jump at Currie point of the compound were 143 K and 47.2 J·kg-1·K-1, respectively.Thermomagnetic properties of the new compound Dy6FeSb2 were investigated by vibrating sample magnetometer.
