Noise in a thin metallic medium: The connection with nonlinear behaviour

View publication

Abstract

At high transition densities the noise in thin metallic films with longitudinal orientation shows an anomalous increase. At the same time, the medium becomes nonlinear, that is, superposition of isolated pulses no longer applies. Measurements of both effects suggest that they are related. The anomalous increase in the noise is seen to be the consequence of the increase in nonlinearity as transition spacing is reduced. Nonlinear behaviour is also responsible for the significant dependence of the noise on the recorded data pattern. © 1988 IEEE
