Point-contact Andreev-reflection spectroscopy of doped manganites: Charge carrier spin-polarization and proximity effects (Review Article)
Materials with spin-polarized charge carriers are the most demanded in the spin-electronics. Particularly requested
 are the so-called half-metals which have the maximum attainable value of carrier spin polarization. Doped
 manganites are in the list of compounds with, potentially, h...

| description | Materials with spin-polarized charge carriers are the most demanded in the spin-electronics. Particularly requested
are the so-called half-metals which have the maximum attainable value of carrier spin polarization. Doped
manganites are in the list of compounds with, potentially, half-metallic properties. The point-contact (PC) Andreevreflection
(AR) spectroscopy is a robust and direct method to measure the degree of current spin polarization. In this
report, advances in PCAR spectroscopy of ferromagnetic manganites are reviewed. The experimental results obtained
on “classic” s-wave superconductor — ferromagnetic manganites PCs, as well as related theoretical models
applied to deduce the actual value of charge carrier spin-polarization, are discussed. Data obtained on “proximity affected”
contacts is also outlined. Systematic and repeatable nature of a number of principal experimental facts detected
in the AR spectrum of proximity affected contacts suggests that some new physical phenomena have been
documented here. Different models of current flow through a superconductor–half-metal ferromagnet interface, as
well as possibility of unconventional superconducting proximity effect, have been discussed.
