Abstract
Elastic constants of polycrystalline L10 FePt are studied from room temperature up to 1073 K by the electromagnetic acoustic resonance. The longitudinal-wave stiffness and the bulk modulus show intermediate values of polycrystalline Fe and Pt, but the shear modulus and Young's modulus show larger value than those of polycrystalline Fe and Pt. The Blackman diagram indicates that L10 FePt exhibits a tendency toward covalent-bond characteristic. Strong anharmonicity of the interatmoic potential is confirmed from the temperature coefficient of the bulk modulus. © 2013 AIP Publishing LLC.
