Abstract :
A remote temperature sensing method is presented which uses the temparature dependence of the ferrimagnetic resonance frequency in iron garnet spheres. The garnet material parameters are discussed for optimizing the measuring sensitivity and the temperature resolution. An accuracy of 0.3°C in the range of 35 to 50°C has been achieved.
