Claim:
1. A magnetoresistive effect oscillator comprising: a magnetoresistive effect element including a first magnetic layer, a second magnetic layer, and a spacer layer sandwiched between the first magnetic layer and the second magnetic layer; and a current applying unit that applies a current to the magnetoresistive effect element to make the magnetoresistive effect element oscillate at a predetermined oscillation frequency, wherein, starting from a state of applying a current having a first current density to the magnetoresistive effect element and holding the magnetoresistive effect element in an oscillating condition, the current applying unit applies a current, which has a second current density and flows in a direction reversed to a direction of the current having the first current density, to the magnetoresistive effect element such that oscillation of the magnetoresistive effect element disappears.
