Phase transformation, damping, and magnetic properties of a Mn 75.7Pt24.3 (at.%) alloy were characterized. It was observed that Mn75.7Pt24.3 exhibits a stable phase transformation in the temperature range of 180-200 C with a small temperature hysteresis and maximum transformation strain of ∼0.5%. The crystal structures and lattice parameters of the transforming phases were determined, where both the high and low temperature phases have a face-centered cubic structure but with different lattice parameters. Finally, it was revealed that the alloy possesses high damping capacity (average Tan Delta of 0.16) during phase transformation.
