Abstract

Abstract:

[AlN/FePt]₁₀, [AlN/FePt]10/Ag and Ag/[AlN/FePt]₁₀ thin films were deposited by magnetron sputtering onto 7059 glass substrates, then were annealed at 550°C for 30 min. It is found that introducing non-magnetic Ag underlayer can improve the ordering and (001) preferred orientation of FePt grains. Furthermore, the (001) texture of FePt grains increases with increasing Ag underlayer thickness. However, with Ag top layer given, it can only be observed that the ordering of FePt grains was promoted.

Key words: [AlN/FePt]₁₀, Ag layers, Ordering of FePt grains, (001) texture
