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…
Anisotropic Magnetoresistance and Magnetic Anisotropy in High-quality (Ga,Mn)As Films
K. Y. Wang, K. W. Edmonds, R. P. Campion +3
We have performed a systematic investigation of magnetotransport of a series of as-grown and annealed Ga1-xMnxAs samples with 0.011 <= x <= 0.09. We find that the anisotropic magne…
Phonon drag thermopower and weak localization
A. Miele, R. Fletcher, E. Zaremba +3
Previous experimental work on a two-dimensional (2D) electron gas in a Si-on-sapphire device led to the conclusion that both conductivity and phonon drag thermopower are affe…
Critical Collapse of the Exchange Enhanced Spin Splitting in 2-D Systems
D. R. Leadley, R. J. Nicholas, J. J. Harris +1
The critical filling factor v_c where Shubnikov-de Haas oscillations become spin split is investigated for a set of GaAs-GaAlAs heterojunctions. Finite temperature magnetoresistanc…
Pulsed Magnetic Field Measurements of the Composite Fermion Effective Mass
D. R. Leadley, M. van der Burgt, R. J. Nicholas +2
Magnetotransport measurements of Composite Fermions (CF) are reported in 50 T pulsed magnetic fields. The CF effective mass is found to increase approximately linearly with the eff…
