Abstract
A magnetic oscillating device including a first magnetic resonance layer with a first magnetic resonance frequency f1, a second magnetic resonance layer with a second magnetic resonance frequency f2 higher than the first magnetic resonance frequency f1, a nonmagnetic layer sandwiched between the first magnetic resonance layer and the second magnetic resonance layer, and a pair of electrodes which supplies a current perpendicularly to film planes of the first and second magnetic resonance layers, in which a difference (f2−f1) between the two magnetic resonance frequencies is larger than half a resonance line width of the first magnetic resonance layer, and a ratio of the two magnetic resonance frequencies f2/f1 is 1.6 or less.
