Spin polarization measurements using PC Andreev Reflection


With the advent of "Spintronics" determining the degree of spin polarization in ferromagnets has gained particular significance. Point Contact Andreev reflection provides one of the simplest techniques to measure the transport spin polarization at Fermi level in ferromagnets. One of our major areas of research is to experimentally determine the spin polarization in ferromagnets that could be potentially useful as spin source in spintronic devices. An extension of this work is to investigate how the process of Andreev reflection gets modified when a superconductor is in contact with a normal metal with strong ferromagnetic spin fluctuations.
