He(+)离子辐照引起的界面混合改变了铂/钴/铂夹心材料的磁性。可以控制磁各向异性的强烈降低(从而降低矫顽力和居里温度)，而不会显著改变样品的粗糙度或光学性质。这开启了开发平面技术的令人兴奋的可能性，通过通过光刻限定的掩模辐射来图案化多层膜的磁性。(C)1999 Elsevier Science B.V.保留所有权利。
He(+) ion irradiation-induced interface mixing modifies the magnetic properties of Pt/Co/Pt sandwiches. A strong decrease in magnetic anisotrophy (hence of the coercivity and Curie temperature) can be controlled without significant changes in sample roughness or optical properties. This opens exciting possibilities to develop a planar technology to pattern the magnetic properties of multilayers by irradiation through a lithographically defined mask.
