In this article, we present the conception of a temperature sensor based on a ferromagnetic microwire having a diameter of about 100~mu ext{m} and a composition of CoFeSiB as 80% Co-Fe and 20% Si-B. We experimentally analyze the influence of the temperature and excitation frequencies on the hysteresis loop of the material. Discussion about how the temperature can act as a measurand through the analysis of the output of the sensor is carried out. Temperature is correlated with the magnetic characteristic of the material, and the results are addressed in light of the recent literature and of the Ising model. All measurements were performed under controlled conditions. An ad hoc setup was developed, and an experimental analysis was carried out to characterize the microwire temperature sensor.

Abstract

In this article, we present the conception of a temperature sensor based on a ferromagnetic microwire having a diameter of about 100~mu ext{m} and a composition of CoFeSiB as 80% Co-Fe and 20% Si-B. We experimentally analyze the influence of the temperature and excitation frequencies on the hysteresis loop of the material. Discussion about how the temperature can act as a measurand through the analysis of the output of the sensor is carried out. Temperature is correlated with the magnetic characteristic of the material, and the results are addressed in light of the recent literature and of the Ising model. All measurements were performed under controlled conditions. An ad hoc setup was developed, and an experimental analysis was carried out to characterize the microwire temperature sensor.
