This research work was aimed to find the composition of equiatomic Fe-Rh alloy and to find the way of preparation of samples with extremely narrow thermal hysteresis and repeatable results. Alloys with content of Fe from 48 up to 52 at.% were examined. Fe-Rh alloys were prepared in forms of bulk piece, plate and wire. The plates of alloys were found to be more perspective for further investigations. The influence of parameters of ingot and samples treatments on antiferromagnetic-ferromagnetic transition was studied. The ways of narrowing of temperature hysteresis were established.
