Structural, magnetic, and transport properties of CoFeSi Heusler films
H. Schneider, Ch. Herbort, G. Jakob +3
We report the deposition of thin CoFeSi films by RF magnetron sputtering. Epitaxial (100)-oriented and L2 ordered growth is observed for films grown on MgO(100) substrates.…
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…
Epitaxial film growth and magnetic properties of Co_2FeSi
H. Schneider, G. Jakob, M. Kallmayer +7
We have grown thin films of the Heusler compound Co_2FeSi by RF magnetron sputtering. On (100)-oriented MgO substrates we find fully epitaxial (100)-oriented and L2_1 ordered growt…
Electronic structure and spectroscopy of the quaternary Heusler alloy CoCrFeAl
Sabine Wurmehl, Gerhard H. Fecher, Kristian Kroth +8
Quaternary Heusler alloys CoCrFeAl with varying Cr to Fe ratio were investigated experimentally and theoretically. The electronic structure and spectroscopic…
Half-metallic ferromagnetism with high magnetic moment and high Curie temperature in CoFeSi
Sabine Wurmehl, Gerhard H. Fecher, Vadim Ksenofontov +4
CoFeSi crystallizes in the ordered L2 structure as proved by X-ray diffraction and Mößbauer spectroscopy. The magnetic moment of CoFeSi was measured to be about …
Investigation of CoFeSi: The Heusler compound with Highest Curie Temperature and Magnetic Moment
Sabine Wurmehl, Gerhard H. Fecher, Hem Chandra Kandpal +3
This work reports on structural and magnetic investigations of the Heusler compound CoFeSi. X-Ray diffraction and Mößbauer spectrometry indicate an ordered structure. Ma…
