摘要：

We present in this paper the experimental results of magnetothermal properties in Dy films and their comparison with the theoretical modeling of the same data. We consider the temperature interval between 80 and 200 K, where Dy is ferromagnetic in low-temperature regions and helimagnetic for high temperatures. Our findings show that due to different phases in the considered temperature interval, the Dy induces thermal hysteresis in specific applied fields. We found that the ferromagnetic phase is favored in the heating process, and in the cooling process, the helimagnetic phase is favored.
