Geometric, electronic, and magnetic structure of Co/sub 2/FeSi: Curie temperature and magnetic moment measurements and calculations
Wurmehl, Sabine; Fecher, Gerhard H.; Kandpal, Hem Chandra; Ksenofontov, Vadim; Felser, Claudia; Lin, Hong-Ji; Morais, Jonder (2005) [Artigo de periódico]In this work a simple concept was used for a systematic search for materials with high spin polarization. It is based on two semiempirical models. First, the Slater-Pauling rule was used for estimation of the magnetic ... -
Large resistivity change and phase transition in the antiferromagnetic semiconductors LiMnAs and LaOMnAs
Beleanu, Andreea; Kiss, Janos; Kreiner, Guido; Köhler, Christian; Müchler, Lukas; Schnelle, Walter; Burkhardt, Ulrich; Chadov, Stanislav; Medvediev, Sergiy; Ebke, Daniel; Felser, Claudia; Cordier, Gerhard; Albert, Barbara; Hoser, Andreas; Bernardi, Fabiano; Larkin, Timofei I.; Pröpper, Daniel; Boris, Alexander V.; Keimer, Bernhard (2013) [Artigo de periódico]Antiferromagnetic semiconductors are new alternative materials for spintronic applications and spin valves. In this work, we report a detailed investigation of two antiferromagnetic semiconductors AMnAs (A = Li, LaO), which ... -
