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…
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…
One-Dimensional Alignment of Nanoparticles Via Magnetic Sorting
R. Bouskila, R. McAloney, S. Mack +3
Near room temperature, thin films of MnAs spontaneously align into two phases, one ferromagnetic and the other paramagnetic. These two phases take the intriguing form of nanoscale…
Optical Properties of III-Mn-V Ferromagnetic Semiconductors
K. S. Burch, D. D. Awschalom, D. N. Basov
We review the first decade of extensive optical studies of ferromagnetic, III-Mn-V diluted magnetic semiconductors. Mn introduces holes and local moments to the III-V host, which c…
Electrodynamics of the vanadium oxides VO2 and V2O3
M. M. Qazilbash, A. A. Schafgans, K. S. Burch +5
The optical/infrared properties of films of vanadium dioxide (VO2) and vanadium sesquioxide (V2O3) have been investigated via ellipsometry and near-normal incidence reflectance mea…
Impurity Band Conduction in a High Temperature Ferromagnetic Semiconductor
K. S. Burch, D. B. Shrekenhamer, E. J. Singley +7
The band structure of a prototypical dilute ferromagnetic semiconductor, GaMnAs, is studied across the phase diagram via optical spectroscopy. We prove that the Fermi…
