Abstract: The superconductor/ferromagnet proximity effect in the Pb/Co$_2$Cr$_{1-x}$Fe$_x$Al bilayer systems has been studied. Thin films of the Heusler alloy Co$_2$Cr$_{1-x}$Fe$_x$Al have been prepared at different substrate temperatures. It has been established using Andreev spectroscopy of point contacts that the degree of spin polarization of conduction electrons in the Heusler alloy is on the order of 30 and 70% for the films prepared at a substrate temperature of 300 and 600 K, respectively. It has been found that the dependence of the superconducting transition temperature on the thickness of the Pb layer at a fixed thickness of the Heusler layer is determined by the degree of spin polarization of the conduction band in the ferromagnetic layer.
