An infrared probe of the insulator-to-metal transition in GaMnAs and GaBeAs
B. C. Chapler, R. C. Myers, S. Mack +8
We report infrared studies of the insulator-to-metal transition (IMT) in GaAs doped with either magnetic (Mn) or non-magnetic acceptors (Be). We observe a resonance with a natural…

Phonon driven spin distribution due to the spin-Seebeck effect
C. M. Jaworski, J. Yang, S. Mack +3
Here we report on measurements of the spin-Seebeck effect of GaMnAs over an extended temperature range alongside the thermal conductivity, specific heat, magnetization, and thermoe…
