Abstract

We report on the low temperature (T = 10 K) magnetoelastic resonance in ribbons of magnetic amorphous alloys, with the goal of assessing their potential for cryogenic temperature sensors. The resonance frequency was found to be nearly temperature independent below T≈150 K, while the amplitude continues to increase upon cooling over the entire temperature range. Furthermore, the magnetic field dependence of the resonant frequency at low (10 K) and high temperatures (300 K) are very similar, suggesting great potential for developing sensors with high stability level over a broad temperature range, especially in the cryogenic regime.
