Bauer, G.E.W. Maekawa, S. Brataas, A. Faculty Applied Sciences Department Kavli Institute of Nanoscience Date 2009-05-12 Abstract Spin pumping by a moving magnetization gives rise to an electric voltage over a spin valve. Thermal fluctuations of the magnetization manifest themselves as increased thermal voltage noise with absorption lines at the ferromagnetic resonance frequency and/or zero frequency. The effect depends on the magnetization configuration and can be of the same order of magnitude as the Johnson-Nyquist thermal noise. Measuring colored voltage noise is an alternative to ferromagnetic resonance experiments for nanoscale ferromagnetic circuits.
