| contents | Spin noise spectroscopy is a technique to measure magnetization fluctuations, a subject of increasing relevance in ultrafast spintronics. We investigate numerically the equilibrium spin noise of ferro- and antiferromagnets within an atomistic spin model. The aim is to predict the possible outcomes of ultrafast spin-noise spectroscopy measurements and demonstrate what relevant information can be extracted. Specifically, we show how this method can be used to determine phase transitions, frequencies of magnon modes and correlation times. |
