An Fe&#x2014;Co&#x2014;Al alloy magnetic thin film contains, in terms of atomic ratio, 20% to 30% Co and 1.5% to 2.5% Al. The Fe&#x2014;Co&#x2014;Al alloy magnetic thin film has a crystallographic orientation such that the (100) plane is parallel to a substrate surface and the &#x3c;100&#x3e; direction is perpendicular to the substrate surface. The Fe&#x2014;Co&#x2014;Al alloy magnetic thin film has good magnetic properties, that is, a magnetization of 1440 emu/cc or more, a coercive force of less than 100 Oe, a damping factor of less than 0.01, and an FMR linewidth &#x394;H at 30 GHz of less than 70 Oe.
