Electric-field control of surface magnetic anisotropy: a density functional approach
2009 (English)In: NEW JOURNAL OF PHYSICS, ISSN 1367-2630 , Vol. 11, no 043007Article in journal (Refereed) Published
In a recent experiment, Weisheit et al ( 2007 Science 315 349) demonstrated that the coercivity of thin L1(0) FePt and FePd films can be modified by the external electric field in an electrochemical environment. Here, this observation is confirmed by density functional calculations for the intrinsic magnetic anisotropy. The origin of the effect is clarified by means of a general and simple method to simulate charged metal surfaces. It is predicted that the coercivity of thin CoPt films is much more susceptible to electric field than that of FePt films.
