Backflow Effect on Spin Diffusion Near Ferromagnet-Superconductor Interface
M. Faiz, R. P. Panguluri, B. Nadgorny +4
The behavior of spin propagation in metals in various measurement schemes is shown to be qualitatively different than a simple exponential decay - due to the backflow effect on spi…
Double-percolation and magnetoresistance effects in ferromagnet-superconductor nanoparticle composites
Xiangdong Liu, Raghava P. Panguluri, Daniel P. Shoemaker +2
We investigate transport and magnetotransport properties of binary networks composed of superconducting (MgB2) and ferromagnetic (CrO2 or LSMO) nanoparticles. While for the LSMO/Mg…
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…
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…
