摘要：This radio-frequency oscillator includes a magnetoresistive device in which aspin-polarised electric current flows. This device comprises a stack of at least a first so-called “anchored” magnetic layer having a fixed magnetisation direction, a second
magnetic layer, an amagnetic layer inserted between the above-mentioned two layers,intended to ensure magnetic decoupling of said layers. The oscillator also comprisesmeans of causing a flow of electrons in said layers perpendicular to these layers and, ifapplicable, of applying an external magnetic field to the structure. The second magneticlayer has an excitation damping factor at least 10% greater than the damping measuredin a simple layer of the same material having the same geometry for magnetic excitationhaving wavelengths equal to or less than the extent of the cone or cylinder of currentthat flows through the stack that constitutes the magnetoresistive device.
