In the present work we have investigated the influence of the thermocycling on the magnetoelastic parameters (the ΔЕ-effect) of amorphous Fe75Si10B15 wires, which had been pretreated by dc current j with simultaneous applying of the tensile stresses σ. It was figured out the ΔЕ-effect behavior depends strongly on pretreatment circumstances. Namely, we have got the maximum absolute value of the ΔЕ-effect shifted into direction of the higher magnetic field magnitude at j<39 MA/m2 and σ<127 MPa. In addition, the negative ΔЕ-effect was not observed for samples, pretreated at j≥45MА/m2 or σ≥128 MPa . The features of such a behavior of the ΔЕ-effect were explained in terms of the magnetoelastic coupling between the inner core and the outer shell of the amorphous wire.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
