Anisotropic magnetoresistance in a 2DEG in a quasi-random magnetic field
A. W. Rushforth, B. L. Gallagher, P. C. Main +4
We present magnetotransport results for a 2D electron gas (2DEG) subject to the quasi-random magnetic field produced by randomly positioned sub-micron Co dots deposited onto the su…
Anisotropic Magnetoresistance in GaMnAs films
K. Y. Wang, K. W. Edmonds, R. P. Campion +5
The magnetoresistance in a series of Ga1-xMnxAs samples with 0.2 =< x =< 0.8 have been measured for three mutually orthogonal orientations of the external magnetic field. The aniso…
High Curie temperature GaMnAs obtained by resistance-monitored annealing
K. W. Edmonds, K. Y. Wang, R. P. Campion +4
We show that by annealing Ga1-xMnxAs thin films at temperatures significantly lower than in previous studies, and monitoring the resistivity during growth, an unprecedented high Cu…
Magnetoresistance and Hall Effect in the Ferromagnetic Semiconductor GaMnAs
K W Edmonds, R P Campion, K-Y Wang +4
The resistivity, temperature, and magnetic field dependence of the anomalous Hall effect in a series of metallic Ga1-xMnxAs thin films with 0.015=<x=<0.08 is presented. A quadratic…
The Hall effect and hole densities in high Tc GaMnAs thin films
K. W. Edmonds, K. Y. Wang, R. P. Campion +4
By studying the Hall effect in a series of low resistivity Ga1-xMnxAs samples, accurate values for the hole density p, Mn concentration x, and Curie temperature Tc are obtained ove…
