In this study, the performance of a current sensor based on giant magnetostrictive materials (GMM) and fiber Bragg grating (FBG) has been improved by optimizing spectral characteristics gratings. By analyzing influence FBG characteristics, three key parameters (gate region length, refractive index modulation depth, toe cutting system) are selected for optimization. The optimal determined to imp...

This paper presents a study of magnetoelectric (ME) properties the PZT/Terfenol-D composite with varying number layers. The consists piezoelectric and magnetostrictive phases that are mechanically coupled. purpose this setup is to gain control over electric polarization material via an external magnetic field. Unlike most similar composites, our samples utilize commercial patch instead pure PZT...

Magnetoelectric (ME) multiferroics are materials in which ferromagnetism and ferroelectricity occur simultaneously and coupling between the two is enabled. Applied magnetic field H gives rise to an induced polarization P which can be expressed in terms of magnetic field by the expression, P=┙H, where ┙ is the ME-susceptibility tensor. Most of the known single-phase ME materials are known to sho...

A variety of extremely high-sensitivity, room-temperature magnetic-field sensors have been fabricated and tested using single-mode fibers in conjunction with highly magnetostrictive metallic glasses. Minimum detectable fields of 5 x 10(-9) Oe/m fiber are reported. The typical characteristics of the fiber magnetometers are summarized.

The influence of multi-cracking on the magnetic response more (Co) or less (Ni78Fe22) magnetostrictive ferromagnetic nanofilms flexible substrates has been studied by combining tensile tests with in situ magneto-optical Kerr effect magnetometry measurements, up to large strain (20%). results show that variations features are significant elastic domain (before cracking), while they slightly affe...
