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…
Realization of spin gapless semiconductors: the Heusler compound Mn2CoAl
Siham Ouardi, Gerhard H. Fecher, Jürgen Kübler +1
Recent studies have reported an interesting class of semiconductor materials that bridge the gap between semiconductors and halfmetallic ferromagnets. These materials, called spin…
Hard X-ray photoelectron spectroscopy on buried, off-stoichiometric CoxMnyGez (x : z = 2 : 0.38) Heusler thin films
Siham Ouardi, Gerhard H. Fecher, Stanislav Chadov +5
Fully epitaxial magnetic tunnel junctions (MTJs) with off-stoichiometric Co2-based Heusler alloy shows a intense dependency of the tunnel magnetoresistance (TMR) on the Mn composit…
Electronic and crystalline structures of zero band-gap PdLuBi thin films grown epitaxially on MgO(100)
Rong Shan, Siham Ouardi, Gerhard H. Fecher +8
Thin films of the proposed topological insulator PdLuBi - a Heusler compound with the C1b structure - were prepared on Ta-Mo-buffered MgO(100) substrates by co-sputtering from PdBi…
