Visiting Assistant Professor of Physics Barry Costanzi published a paper titled “Noise in Mesoscale Magnetic Dots from Random Telegraph Noise to 1/f Noise” in the journal IEEE Transactions on Magnetics, with collaborators from the University of Minnesota and from Honeywell International Inc. The paper discusses experimental work on the characterization and engineering of thermal fluctuations (or “noise”) in magnetic samples on the mesoscale (~100s of nm in size), with applications toward explaining the origin of noise signals in many other physical systems. Costanzi also presented his work in an invited talk at the International Conference on Magnetism in San Francisco this summer.
