L10 ordered FePtPd alloy films, with strong perpendicular magnetic anisotropy, are leading candidates for recording media in next-generation hard disk drives and solid state magnetic random access memory (MRAM) technologies. The magnetostrictive properties of such materials are of importance, as strain thereby in these systems will impact their magnetic switching characteristics. In heat assisted magnetic recording, for example, the medium experiences large strains due to thermal expansion during recording, while MRAM bit cells are often subject to large process-induced strains. Further, the discovery or design of a highly magnetostrictive, high-anisotropy material would be advantageous to the development of strain-assisted magnetic recording [1] or MRAM based on synthetic multiferroics [2].
