Abstract: When enough spin-polarised current crosses a thin ferromagnetic film through a nanoscale contact, the local magnetisation might describe high-frequency oscillations in the mi-crowave spectrum band that can then propagate through the film in form of spin waves. Devices that transform direct current into spin-wave excitations, so called spin torque nano-oscillators (STNO),are promising candidates into a new era of nanotechnology, with possible applications in mobile communications or in computation. Combining STNO with different currents in the same film can lead to the synchronisation of their frequencies, describing static and dynamic interference patterns In this paper we simulate systems with one and two STNO and characterise their oscillations and synchronisation conditions
