Ferromagnetism and infrared electrodynamics of GaMnAs}
B. C. Chapler, S. Mack, R. C. Myers +7
We report on the magnetic and the electronic properties of the prototype dilute magnetic semiconductor GaMnAs using infrared (IR) spectroscopy. Trends in the ferromagne…
Infrared conductivity of hole accumulation and depletion layers in (Ga,Mn)As- and (Ga,Be)As-based electric field-effect devices
B. C. Chapler, S. Mack, L. Ju +11
We have fabricated electric double-layer field-effect devices to electrostatically dope our active materials, either =0.015 GaMnAs or =3.2 Ga$_{1-x…
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…
Oscillatory Spin Polarization and Magneto-Optic Kerr Effect in Fe3O4 Thin Films on GaAs(001)
Yan Li, Wei Han, A. G. Swartz +5
The spin dependent properties of epitaxial Fe3O4 thin films on GaAs(001) are studied by the ferromagnetic proximity polarization (FPP) effect and magneto-optic Kerr effect (MOKE).…
Epitaxial EuO Thin Films on GaAs
A. G. Swartz, J. Ciraldo, J. J. I. Wong +7
We demonstrate the epitaxial growth of EuO on GaAs by reactive molecular beam epitaxy. Thin films are grown in an adsorption-controlled regime with the aid of an MgO diffusion barr…
