“…1 It has been reported that substitution of small amounts of elements such as Co, Al, Ru, Ir, Os, and Re stabilizes the low-temperature dynamic AFM phase in CeFe 2 . 3,[5][6][7] The coexistence of FM and AFM phases across the AFM-FM transition in the case of Ru-doped CeFe 2 has been shown by Hall probe imaging, and this transition bears distinct signatures of first-order phase transition, namely, supercooling, superheating, and time relaxation. 8 Very sharp magnetization step across the fieldinduced AFM-FM transition has been reported at temperatures less than 5 K when CeFe 2 is doped with Ru and Re.…”
