摘要:

A new method for determining the transport spin-polarization, point contact tunneling from a low temperature superconductor into a ferromagnet, is used to determine the spin polarization of several LaSrMnO thin films and crystals. The Andreev reflection process and its utility in measurements of spin-polarization are described. Preliminary results for the spin polarization of LSMO are presented. ©1999 American Institute of Physics.
