摘要
A magnetoresisive sensor having a thin seed layer that provides an exceptionally smooth interface between layers of the sensor stack. The exceptionally smooth interface provided by the seed layer reduces interlayer exchange coupling allowing the non-magnetic spacer layer (or barrier layer) to be very thin. The seed layer includes a thin layer of Ru and a thin layer of Si which intermix to form a homogeneous, amorphous thin seed layer of Ru-silicide.
