The properties of magnetic film edges can determine the behavior of small patterned elements, either by proximity in the smallest elements or because reversal often nucleates at an edge in larger elements. Three classes of nonideal edges are also modeled: tilted edge surfaces, reduced spontaneous magnetization near the edge, and surface anisotropy on the edge surface.","PeriodicalId":262607,"journal":{"name":"INTERMAG 2006 - IEEE International Magnetics Conference","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134322236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The energy barriers for diffusion behavior and magnetic properties, including the spin polarizations (SPs) and magnetic moments, were calculated for Fe/MgO (001) and Co/MgO (001) systems. According to the potential energy surface (PES) calculation for the Fe/MgO (001) system, the most stable adsorption site was the hollow site where the Ead was 0.28 eV/(2 x 2). Mg and O atoms of the surface plane participated the bonding with the adsorbed Fe adatom representing the configuration of C2v symmetry. The bond lengths of Fe-Mg and Fe-0 were 2.31 A and 2.00 A, respectively.The magnetic moment of hollow site-adsorbed Fe atom was reduced to 2.99 mu B from 3.50 mu B of in vacuum state.
