Direct Measurement of Magnetic Noise

Keywords: Magnetic

Often magnetic noise in metallic ferromagnets is measured indirectly by measuring the resistivity.  We are seeking a postdoc to investigate a novel, more general concept for using magnetic sensors to directly measure magnetic fluctuations in thin films and nanoparticles.  The sensors will be either spin valves or magnetic tunnel junctions.  The initial focus of the research will be on using thin film lithography and signal processing techniques to validate this new approach.  Once the method is developed, the initial application of the technique will be to make magnetic noise measurements near the Curie point of thin film ferromagnets.  The work will be carried out in close collaboration with Professor Ed Nowak at the University of Delaware
