Inelastic Scattering and Spin Polarization in Dilute Magnetic Semiconductor (Ga,Mn)Sb
Raghava P. Panguluri, B. Nadgorny, T. Wojtowicz +2
The Point Contact Andreev Reflection (PCAR) technique has already been used to measure the spin polarization of some of the dilute magnetic semiconductors, such as narrow-band (In,…
Andreev Reflection and Pair Breaking Effects at the Superconductor/Magnetic Semiconductor Interface
R. P. Panguluri, K. C. Ku, T. Wojtowicz +5
We investigate the applicability of spin polarization measurements using Andreev reflection in a point contact geometry in heavily doped dilute magnetic semiconductors, such as (Ga…
Spin Polarization and Electonic Structure of Room-Curie Ferromagnetic Mn5Ge3 Epilayers
R. P. Panguluri, Changgan Zeng, H. H. Weitering +3
Germanium-based alloys hold great promise for future spintronics applications, due to their potential for integration with conventional Si-based electronics. Mn5Ge3 exhibits strong…
Measurement of Spin Polarization by Andreev Reflection in Ferromagnetic In1-xMnxSb Epilayers
R. P. Panguluri, B. Nadgorny, T. Wojtowicz +3
We carried out Point Contact Andreev Reflection (PCAR) spin spectroscopy measurements on epitaxially-grown ferromagnetic In1-xMnxSb epilayers with a Curie temperature of ~9K. The s…
Point Contact Spin Spectroscopy of Ferromagnetic MnAs Epitaxial Films
R. Panguluri, G. Tsoi, B. Nadgorny +3
We use point contact Andreev reflection spin spectroscopy to measure the transport spin polarization of MnAs epitaxial films grown on (001) GaAs. By analyzing both the temperature…
