a–c show the magnetization as a function of magnetic field. It reveals magnetic hysteresis loops, and the coercive field is roughly 0.02 T. d–f show the temperature-dependent magnetization of field-cooled and zero-field-cooled processes. It splits from 330 to 2 K. a–f support the ferromagnetic characteristic in the \(\hbox{WSe}_{2-x}\hbox{Te}_{x}\) single crystals
