摘要：

The　3d　transition　metals　such　as　iron,　cobalt,　and　their　alloys　bear　high　saturation　magnetization　(Ms)　and　high　Curie　temperatures　(TC),　which　are　necessary　for　the　giant　energy　product　and　good　thermal　stability,　respectively.　For　the　nanowire　of　3d　transition　metals,　such　as　Co　nanowires,　the　effective　anisotropy　field　can　be　as　much　as　16.5　kOe　by　combining　the　shape　anisotropy　and　magnetocrystalline　anisotropy.　However,　such　high　coercivity　has　never　been　achieved,　because　there　are　much　defects　and　the　easy　axis　deviation　from　the　length　direction　for　the　nanowires.　Therefore,　in　this　study,　we　investigate　the　influence　of　the　defects　and　deviation　of　easy　axis　on　the　coercivity　and　magnetization　reversal　process　via　3D　micromagnetic　simulations.　©　2018　IEEE.
