First-principles study of the structural stability of Mn3Z (Z=Ga, Sn and Ge) Heusler compounds
Delin Zhang, Binghai Yan, Shu-Chun Wu +4
We investigate the structural stability and magnetic properties of cubic, tetragonal and hexagonal phases of Mn3Z (Z=Ga, Sn and Ge) Heusler compounds using first-principles density…
On the half-metallicity of Co2FeSi Heusler alloy: an experimental and ab initio study
L. Makinistian, Muhammad M. Faiz, Raghava P. Panguluri +6
Co2FeSi, a Heusler alloy with the highest magnetic moment per unit cell and the highest Curie temperature, has largely been described theoretically as a half-metal. This conclusion…
Magnetic and transport properties of tetragonal- or cubic-Heusler-type Co-substituted Mn-Ga epitaxial thin films
Takahide Kubota, Siham Ouardi, Shigemi Mizukami +4
The composition dependence of the structural, magnetic, and transport properties of epitaxially grown Mn-Co-Ga films were investigated. The crystal structure was observed to change…
Perpendicularly magnetized Mn-Co-Ga-based thin films with high coercive field
Siham Ouardi, Takahide Kubota, Gerhard H. Fecher +5
MnCoGa epitaxial thin films were grown on MgO substrates by magnetron co-sputtering. Structures were tetragonal or cubic depending on Co content. Composition dependen…
Magnetic dichroism in angular resolved hard X-ray photoelectron spectroscopy from buried magnetic layers
Carlos E. ViolBarbosa, Siham Ouardi, Gerhard H. Fecher +2
This work reports on the measurement of magnetic dichroism in angular-resolved photoelectron spectroscopy from in-plane magnetized buried thin films. The high bulk sensitivity of h…
Topological surface states of Bi2Se3 with the coexistence of Se vacancies
Binghai Yan, Delin Zhang, Claudia Felser
Although topological surface states are known to be robust against non-magnetic surface perturbations, their band dispersions and spatial distributions are still sensitive to the s…
