Abstract
The present invention relates to a magnetoresistive head having a spin valve MR film for use in a magnetic sensor, a magnetic head or the like. Of two ferromagnetic layers divided by a nonmagnetic metal film, at least ferromagnetic layer on the side being in contact with an antiferromagnetic layer is formed by a cobalt-nickel-iron alloy including at the rate of 5 to 40 atoms % of a nickel and 30 to 95 atoms % of cobalt.
