We nd that Co/W(111) has revealed in-plane ferromagnetic ordered for room temperature growth mode and both of in-plane and perpen- dicular magnetism for low temperature growth mode. Co undergo well epitaxial on W(111) because of the small lattice mismatch in a specic orientaion. Co/faceted Pd/Wf112g reveals two-step hysteresis loops and we infer that alloys are formed. There is 40 Oe reduction in the magnetic coercivity of Co/faceted Pd/Wf112g when 1.8 langmuir hydrogen is dosed with 1.8 Langmuir.皺化磁性晶體結構溫控熱脫附磁光科爾效應歐階電子能譜儀facetedmagnetismcrystalline structureTPDMOKEAES
