22 Aug 2013 | Abstract: | We report the discovery of a new diluted magnetic semiconductor, Li(Zn,Mn)P,
in which charge and spin are introduced independently via lithium
off-stoichiometry and the isovalent substitution of Mn2+ for Zn2+,
respectively. Isostructural to (Ga,Mn)As, Li(Zn,Mn)P was found to be a p-type
ferromagnetic semiconductor with excess Lithium providing charge doping. First
principles calculations indicate that excess Li is favored to partially occupy
the Zn site, leading to hole doping. Ferromagnetism is mediated in
semiconducting samples of relative low mobile carriers with a small coercive
force, indicating an easy spin flip. | Source: | arXiv, 1308.4929 | Services: | Forum | Review | PDF | Favorites |
