摘要： A stack having a seed layer structure with a first part having a first cross-track width and a free layer deposited over the seed layer structure and with a second cross-track width, wherein the first cross-track width is greater than the second cross-track width. In one implementation, the seed layer structure further comprises an antiferromagnetic (AFM) layer and a synthetic antiferromagnetic (SAF) layer. In one alternate implementation, the cross-track width of the seed layer structure is substantially equal to the combined cross-track width of the free layer and cross-track width of two permanent magnets.

摘要： A method of creating a stack having multiple layers of material deposited onto a substrate. The method includes controlling atom mobility to provide a uniform thickness for the deposited layers and increasing or decreasing a deposition temperature to control the atom mobility and/or roughness for the deposited layers. In an illustrated embodiment, the deposition temperature is increased to increase the atom mobility and the deposition temperature is decreased to decrease the atom mobility to control roughness and provide a uniform layer thickness. In another embodiment, the deposition temperature is increased or decreased for different portions of a layer. As described, a first amount of a material is deposited at a first deposition temperature to provide an optimum surface interface with a prior layer and a second amount of the material is deposited at a second deposition temperature to provide a uniform layer thickness.
