Abstract
A spin transfer oscillator including a magnetic stack including at least two magnetic layers, at least one of the two magnetic layers is an oscillating layer that has variable direction magnetization and a current supply device configured to cause the flow of a current of electrons perpendicularly to the plane of the magnetic stack. The magnetic stack includes a device to generate inhomogeneities of current at the level of the surface of the oscillating layer and the intensity of the current supplied by the supply device is selected such that the magnetization of the oscillating layer has a consistent magnetic configuration, the magnetic configuration oscillating as a whole at the same fundamental frequency.
