Tunneling of Bloch electrons through vacuum barrier
I. I. Mazin
Tunneling of Bloch electrons through a vacuum barrier introduces new physical effects in comparison with the textbook case of free (plane wave) electrons. For the latter, the expon…
The origin of high transport spin polarization in LaSrMnO: direct evidence for minority spin states
B. Nadgorny, I. I. Mazin, M. Osofsky +7
Using the point contact Andreev reflection technique, we have carried out a systematic study of the spin polarization in the colossal magnetoresistive manganite, LaSr$_{0.3…
Probing Spin Polarization with Andreev Reflection: A Theoretical Basis
I. I. Mazin, A. A. Golubov, B. Nadgorny
Andreev reflection at the interface between a ferromagnet and a superconductor has become a foundation of a versatile new technique of measuring the spin polarization of magnetic m…
Robust half-metallicity and metamagnetism in Fe_{x}Co_{1-x}S_{2}
I. I. Mazin
The Fe_{x}Co_{1-x}S_{2} system is predicted, on the basis of density functional calculations, to be a half metal for a large range of concentrations. Unlike most known half metals,…
