Abstract

Due to their high magnetic anisotropy, L10-ordered intermetallics when ferromagnetic bear a potential as high density magnetic recording materials. In their case the c-axis of the tetragonally distorted structure is the easy axis of magnetization. We present preliminary results on the details of ordering kinetics on FePd films (thickness 100 nm) epitaxially co-deposited on MgO substrates. From the observation of so called ‘order-order relaxations’ during isothermal small-step anneals monitored by residual electrical resistivity (REST) measurement we determine an ordering activation energy of about 2.4 eV, which is somewhat below the value of 2.7 eV obtained in a previous investigation on bulk material.
