“…4 for DyNi 2 − x A x B 2 C (A = Co and Cr, x = 0.1 and 0.2). For magnetic field changes of 1 and 2 T, − S M is negative (inverse MCE) below the transition temperature, and changes to positive with increasing temperature, this behavior is similar to that of the recently reported Dy 1 − x Ho x Ni 2 B 2 C [17] and RNi 2 B 2 C (R = Dy, Ho, and Er), [18] compounds which can be understood in terms of the FM-AFM phase coexistence and the variation in the ratio of these phases under different magnetic fields. A x B 2 C system with a magnetic field change of 7 T, respectively.…”
