A method of controlling magnetic characteristics of a spin valve effect MR element and a method of controlling magnetic characteristics of a magnetic head with the MR element include a step of supplying direct current with a gradually increasing value to the MR element so as to generate magnetic field in a desired direction and to generate joule heat, the generated magnetic field and the generated joule heat being applied to the MR element, and a step of controlling a magnetization direction caused by exchange coupling in the MR element based upon the applied magnetic field and the applied joule heat.
