Nanogranular TiN-ZrO(2) intermediate layer induced improvement of isolation and grain size of FePt thin films

The effects of TiN-ZrO(2) intermediate layer on the microstructures and magnetic properties of FePt films were investigated. The TiN-ZrO(2) intermediate layer was granular consisting of grains of solid solution of Ti(Zr)ON segregated by amorphous ZrO(2). By doping ZrO(2) into TiN intermediate layer,...

description The effects of TiN-ZrO(2) intermediate layer on the microstructures and magnetic properties of FePt films were investigated. The TiN-ZrO(2) intermediate layer was granular consisting of grains of solid solution of Ti(Zr)ON segregated by amorphous ZrO(2). By doping ZrO(2) into TiN intermediate layer, the FePt grains became better isolated from each other and the FePt grain size was reduced. For 20 vol. % ZrO(2) doping into TiN, the grain size decreased dramatically from 11. 2 nm to 6. 4 nm, and good perpendicular anisotropy was achieved simultaneously. For the FePt 4nm-SiO(2) 35 vol. % -C 20 vol. % films grown on top of the TiN-ZrO(2) 20 vol. % intermediate layer, well isolated FePt (001) granular films with coercivity higher than 18. 1 kOe and an average size as small as 6. 4 nm were achieved.
