摘要：

In this study, magnetic and magnetocaloric properties of GdB2 compound were first time investigated.GdB2 compound was prepared by arc-melting method. The magnetic characterizations of the samples were defined at various temperatures and magnetic fields. Saturation magnetization value is 19.5 emu/g at 275 K. The magnetic entropy change of the GdB2 compound was calculated from the isothermal magnetization curves under the different magnetic fields. The peak value of vertical bar Delta S-m vertical bar is 1.89 J/kg K under the applied field changing from 0 T to 4 T. The adiabatic temperature change was calculated from heat capacity. The peak value of Delta T-ad is 0.49 K at 1 T magnetic field.
