MR devices and associated methods of fabrication are disclosed. An MR device includes an MR element and a bias structure on either side of the MR element for biasing a free layer of the MR element. The bias structure includes an amorphous buffer layer, a first seed layer formed from Cr, a second seed layer formed from a non-magnetic Cr alloy, and a hard bias magnetic layer. The second seed layer formed from the non-magnetic Cr alloy is formed between the Cr seed layer and the hard bias magnetic layer. An example of a non-magnetic Cr alloy is Chromium-Molybdenum (CrMo).
