Abstract
A method including forming a multilayer structure. The multilayer structure includes a seed layer comprising a first component selected from the group consisting of a Pt-group metal, Fe, Mn, Ir and Co. The multilayer structure also includes an intermediate layer comprising the first component and a second component selected from the group consisting of a Pt-group metal, Fe, Mn, Ir and Co. The second component is different than the first component. The multilayer structure further includes a cap layer comprising the first component. The method further includes heating the multilayer structure to an annealing temperature to cause a phase transformation of the intermediate layer. Also a hard magnet including a seed layer comprising a first component selected from the group consisting of a Pt-group metal, Fe, Mn, Ir and Co. The hard magnet also includes a cap layer comprising the first component. The hard magnet further includes an intermediate layer between the seed layer and the cap layer. The intermediate layer includes the first component and a second component selected from the group consisting of a Pt-group metal, Fe, Mn, Ir and Co. The first component is different than the second component. Additionally, a read/write head including the hard magnet.
