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 ... -
Magnetic dichroism in core-level photoemission from Gd(0001)
Morais, Jonder; Fecher, Gerhard H.; Denecke, Reinhard; Hussain, Zahid; Fadley, Charles S. (2000) [Artigo de periódico]This work reports on magnetic dichroism in photoemission from the Gd 4l(l=s,p,d, f) core level of in-plane magnetized Gd films excited with linearly, circularly, and unpolarized light. Thin Gd films of about 100 ML thickness ... -
