摘要：

In this work, we report on the changes in structural and magnetic properties of [Pt (0.7 nm)/Cr (x nm)/Co (0.5 nm)](x) (15)/Si, x = 0.1 and 0.2 nm, due to 10 keV He+-ion irradiation at room temperature in the fluence range of 2 x 10(15)-5 x 10(16) ions-cm(-2). Enhancement in the coercivity values with a fairly square magnetization reversal loop (for both the multilayers), upon irradiation to the fluence of 5 x 10(16) ions-cm(-2) was observed. Above finding is discussed in the realm of ion beam mixing, leading to the CoCrPt ternary alloy phase formation, after low-energy He+-ion irradiation. (C) 2011 Elsevier B.V. All rights reserved.
