摘要：

This paper discusses the effect of ion beam irradiation on the magnetic and structural properties of Pt/Cr/Co multilayers. We observe Co-Cr-Pt ternary alloy phase formation in 1 MeV N+ ion irradiated [Pt (2.5 nm)/Cr (0.8 nm)/Co (3.0 nm)](x6)/Si multilayers for a fluence of 1 X 10(16) ions cm(-2) and beyond. The observed phase formation is accompanied by an enhancement in the average grain size, surface roughness and coercivity. Monte Carlo simulation has been performed to study ion-induced defect evolution and atomic displacements to correlate the above observed effects. (c) 2008 Elsevier B.V. All rights reserved.
