Substituting the main group element in cobalt - iron based Heusler alloys: CoFeAlSi
G. H. Fecher, C. Felser
This work reports about electronic structure calculations for the Heusler compound CoFeAlSi. Particular emphasis was put on the role of the main group element in th…
Calculated electronic and magnetic properties of the half-metallic, transition metal based Heusler compounds
Hem C. Kandpal, Gerhard H. Fecher, Claudia Felser
In this work, results of {\it ab-initio} band structure calculations for Heusler compounds that have and sites occupied by transition metals and by a main group…
High energy, high resolution photoelectron spectroscopy of Co2Mn(1-x)Fe(x)Si
Gerhard H. Fecher, Benjamin Balke, Siham Ouardi +5
This work reports on high resolution photoelectron spectroscopy for the valence band of Co2Mn(1-x)Fe(x)Si (x=0,0.5,1) excited by photons of about 8 keV energy. The measurements sho…
Surface and bulk properties of the Heusler compound Co2Cr0.6Fe0.4Al: a Moessbauer study
Vadim Ksenofontov, Sabine Wurmehl, Sergey Reiman +2
To explore its structural and magnetic properties, the Heusler compound Co2Cr0.6Fe0.4Al was investigated using Moessbauer spectroscopy. The results of both transmission and convers…
Bulk sensitive photo emission spectroscopy of C1b compounds
Gerhard H. Fecher, Andrei Gloskowskii, Kristian Kroth +8
This work reports about bulk-sensitive, high energy photoelectron spectroscopy from the valence band of CoTiSb excited by photons from 1.2 to 5 keV energy. The high energy photoele…
A new diluted magnetic semiconductor: The half-metallic ferromagnet CoTi(1-x)FexSb
Benjamin Balke, Kristian Kroth, Gerhard H. Fecher +1
Half-Heusler compounds with 18 valence electrons are semi-conducting. It will be shown that doping with electrons results in half-metallic ferromagnets, similar to the case of dilu…
