Tetragonal phase of epitaxial room-temperature antiferromagnet CuMnAs
P. Wadley, V. Novák, R. P. Campion +20
Recent studies have demonstrated the potential of antiferromagnets as the active component in spintronic devices. This is in contrast to their current passive role as pinning layer…
CuMn-V compounds: a transition from semimetal low-temperature to semiconductor high-temperature antiferromagnets
F. Maca, J. Masek, O. Stelmakhovych +7
We report on a theoretical and experimental study of CuMn-V antiferromagnets. Previous works showed low-temperature antiferomagnetism and semimetal electronic structure of the semi…
Detection of stacking faults breaking the [110]/[1-10] symmetry in ferromagnetic semiconductors (Ga,Mn)As and (Ga,Mn)(As,P)
M. Kopecky, J. Kub, F. Maca +6
We report high resolution x-ray diffraction measurements of (Ga,Mn)As and (Ga,Mn)(As,P) epilayers. We observe a structural anisotropy in the form of stacking faults which are prese…
Microscopic analysis of the valence band and impurity band theories of (Ga,Mn)As
J. Masek, F. Maca, J. Kudrnovsky +10
We analyze microscopically the valence and impurity band models of ferromagnetic (Ga,Mn)As. We find that the tight-binding Anderson approach with conventional parameterization and…
Antiferromagnetic I-Mn-V semiconductors
T. Jungwirth, V. Novak, X. Marti +14
After decades of research, the low Curie temperature of ferromagnetic semiconductors remains the key problem in the development of magnetic semiconductor spintronic technologies. R…
Dilute moment n-type ferromagnetic semiconductor Li(Zn,Mn)As
J. Masek, J. Kudrnovsky, F. Maca +4
We propose to replace Ga in (Ga,Mn)As with Li and Zn as a route to high Curie temperature, carrier mediated ferromagnetism in a dilute moment n-type semiconductor. Superior materia…
