Mn<sub>5<\/sub>Ge<sub>3<\/sub> on Ge(111) and Mn<sub>5<\/sub>Si<sub>3<\/sub> on Si(111) thin films both exhibit a hexagonal D8<sub>8<\/sub> (P63\/mcm) structure but differ in their magnetic properties, with Mn<sub>5<\/sub>Ge<sub>3<\/sub> being ferromagnetic and Mn<sub>5<\/sub>Si<sub>3<\/sub> displaying complex anti-ferromagnetic behavior. Given their distinct properties, the ternary system Mn<sub>5<\/sub>(Si<sub>x<\/sub>Ge<sub>1-x<\/sub>)<sub>3<\/sub> is also of great interest. Due to the limited previous researches only concerned on bulk and polycrystalline Mn<sub>5<\/sub>(Si<sub>x<\/sub>Ge<sub>1-x<\/sub>)<sub>3<\/sub> system, this study mainly focused on Mn<sub>5<\/sub>(Si<sub>x<\/sub>Ge<sub>1-x<\/sub>)<sub>3<\/sub> thin films. These crystalline thin films were produced using molecular beam epitaxy through the co-deposition of manganese, germanium, and silicon atoms.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sueyeong Kang will speak on 8th of November 2024, at 9 AM in the Raymond Kern Room at CINaM<\/p>\n","protected":false},"author":16,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[5],"tags":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/posts\/13496"}],"collection":[{"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/comments?post=13496"}],"version-history":[{"count":2,"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/posts\/13496\/revisions"}],"predecessor-version":[{"id":13499,"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/posts\/13496\/revisions\/13499"}],"wp:attachment":[{"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/media?parent=13496"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/categories?post=13496"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cinam.univ-mrs.fr\/cinam\/en\/wp-json\/wp\/v2\/tags?post=13496"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
