Abstract
A method has been developed to monitor the change in initial permeability while a sample is being annealed in a rotating magnetic field. RF-sputtered thin films of CoZrNb were placed within a sensing coil that can withstand high temperatures. The self-inductance of the coil was monitored during annealing. The inductance of the coil is a function of the sample permeability. The change in initial permeability as a function of annealing temperature time, and sample deposition conditions was investigated. It was found that there is a range of critical temperatures in which the permeability of the sample increased rapidly, which depends on the deposition temperature of the thin filmKeywords
