“…Additionally, the presence of magnetic hysteresis and thermal hysteresis in these compounds prevents them from operating at high frequencies with fast response. On the contrary, the metallic glasses (MGs) that exhibit a broader −Δ S m peak (−Δ S m peak ) without magnetic hysteresis and thermal hysteresis are preferred, such as Gd-based and Fe-based MGs [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. The tunable Curie temperature ( T c ) in a wide range of composition adjustments is beneficial for constructing the flattened −Δ S m curve [ 15 , 16 , 17 ].…”
