In this paper we present an analysis of temperature response of a 100 μm hysteretic wire exploiting a time domain readout. The ferromagnetic wire is composed of 80% Co-Fe, 20% Si, B. The study here conducted investigates the effect of temperature in the microwire with an output measured as time response, which represents an intriguing method to convert the target quantity. The experiments have been accomplished by using a MuMetal® electromagnetic shield with controlled temperature and an acquisition system to process the output. Results here reported evince the suitability of the proposed method which arouses interest for several interesting applications.
