Magnetization and specific heat studies of Gd2In

We have measured the temperature and magnetic field dependence of the magnetization for Gd2In. The results show that Gd2In exhibits a helical ferromagnetic transition at 190 K and an antiferromagnetic transition at 100 K in zero and low applied fields. Both the helical ferromagnetic state at tempera...

Zusammenfassung:We have measured the temperature and magnetic field dependence of the magnetization for Gd2In. The results show that Gd2In exhibits a helical ferromagnetic transition at 190 K and an antiferromagnetic transition at 100 K in zero and low applied fields. Both the helical ferromagnetic state at temperatures between 100 and 190 K and the antiferromagnetic state at low temperatures are transformed to a simple ferromagnetic state by high applied fields. The antiferromagnetic transition temperature decreases with increasing applied field and approaches zero at H=25 kOe. We have also measured the temperature dependence of the specific heat for Gd2In. The data show two distinct specific heat anomalies which are associated with the two magnetic transitions.
