Abstract

•Two bulk Fe49Rh51 samples produced by two different temperature regimes.•Rapidly quenched (FQ) in iced-water and slow cooled (SC) with rate of 2 K/min.•The effects of cooling rate on the phase transition in Fe49Rh51 were studied.•The temperature of the AFM-FM transition was similar for FQ and SC samples.•Difference in ΔSM(T) curves and magnetization change: sharper changes for FQ sample.•Difference on hysteresis losses values is shown.
