Abstract:
Fe ions with an energy of 40 keV were implanted into Si plates with the fluence varying in the range of (1.6-3.0) × 10 17 ion/cm 2 in the external magnetic field. Scanning magnetooptical Kerr effect (MOKE) studies have shown that all samples possess uniaxial anisotropy. Both the coercive field and the anisotropy field increase with fluence. It was suggested that induced anisotropy is caused by inverse magnetostriction. © 2011 Elsevier B.V. All rights reserved.
