Abstract
A method involves depositing a seed layer comprising at least A1 phase FePt. A main layer of A1 phase FePt is deposited over the seed layer. The main layer includes FePt of a different stoichiometry than the seed layer. The seed and main layers are annealed to convert the A1 phase FePt to L10 phase FePt. The annealing involves heating the substrate prior to depositing at least part of the A1 phase FePt of the main or seed layers.
