A local noise measurement device for magnetic physical systems

Abstract : We present an experimental setup developed to measure locally the fluctuations of the magnetization of physical systems such as spin and superspin glasses. It is based on micronic and submicronic Hall probes. We present the noise reduction at ambient temperature owing to the use of the spinning current technique. Finally, we show why, with such probes, the noise measured on a macroscopic sample probes only a microscopic volume of the sample.
