In this paper the micromagnetic simulation of thermal generation of spin waves in permalloy is shown. The simulation was carried out with MuMax3 software. The relationship between the value of external applied field and frequency of the generated spin waves, as well as the influence of sample temperature on spin waves amplitude were investigated and they are described. Thermal generation of spin waves was simulated for room temperatures.
