Title SPIN OSCILLATION DEVICE AND MANUFACTURING METHOD FOR SAME meetings
Abstract

Provided is a spin oscillation device which adds noise common to a plurality of spin oscillation elements in order to synchronize phases. The present invention is provided with: a spin oscillation element group (12) comprising a plurality of spin oscillation elements (11) wherein a spacer comprising non-magnetic material is sandwiched between 2 ferromagnetic layers comprising ferromagnetic material, and by way of current supplied to the spacer and the ferromagnetic layers, spin torque is exerted in order to generate magnetization by self-oscillation

and noise addition means (13) for adding noise which is common to the plurality of spin oscillation elements (11) and which is of a higher frequency than the oscillation frequency of the spin oscillation elements (11). Furthermore, the trajectory of precession of the magnetization of the spin oscillation elements (11) is controlled by way of physical properties, current and a magnetic field so as to have inflection points such that a small curvature is achieved.
