Description

We report that this alloy has been formed in three phases Dy 5 Si 3 , Dy 3 Co 2.2 Si 1.8 , and Dy 3 Co with
four successive magnetic transitions. The important role in the magnetic behavior plays
competing ferromagnetic and antiferromagnetic interactions in the alloy. The number of
successive magnetic transitions together with competing magnetic interactions exhibit
broadened magnetocaloric effect (MCE) peak with temperature width of ΔT = 83.8 and
93.2 K and consequently a large RC value of 474 and 739 J/kg, for a magnetic field change of
0–5 and 0–7 T, respectively.
