High magnetomechanical coupling on magnetic microwire for sensors with biological applications
In this letter, we report the experimental work carried out to study and improve the magnetomechanical coupling on magnetic microwires. A good magnetoelastic response, with magnetoelastic coupling factor k=0.43, has been obtained by control of both wire diameter and sample microstructure. The study...

| Resumo: | In this letter, we report the experimental work carried out to study and improve the magnetomechanical coupling on magnetic microwires. A good magnetoelastic response, with magnetoelastic coupling factor k=0.43, has been obtained by control of both wire diameter and sample microstructure. The study addresses two following aspects: (a) analysis of the suitability of amorphous magnetoelastic microwire as promising tiny sensor element to be used as wireless biosensors as well as environment detectors. In particular, its potential as liquids viscosity sensor has been confirmed. (b) Study, as the first time in this kind of magnetic microwire, of the effects of nanocrystallization on the sample magnetoelastic behavior. |
