摘要：
A magnetoresistive effect element includes a magnetization fixed layer having substantially fixed magnetization direction. A magnetization variable layer has a variable magnetization direction, consists of a magnetic alloy that has a BCC structure and is expressed by Fe1-x-yCoxNiy (0≦x+y≦1, 0≦x≦1, 0≦y≦1), and contains at least one additive element of V, Cr, and Mn in a range of 0
