ABSTRACT
In this paper magnetic field induced strain (MFIS) of an antiferromagnetic γMn–Fe(Cu) is investigated. It is discovered that there is a high reversible MFIS of 1.6% with positive strain parallel to applied magnetic field at 3.8 T and ultimate negative strain of -0.15% at 1 T in the same way parallel to applied magnetic field after a precompressive stress (strain). The qualitative analysis of positive strain without prestress and the negative strain with precompressive stress under the same condition of applied magnetic field is discussed.

    Magnetostriction “jump” effect often occurs in ferromagnetic materials. However, in this letter, the jump effect is observed in antiferromagnetic face-centered-cubic austenitic polycrystalline Mn42Fe58 alloy at room temperature. The magnetostriction under an applied field of 1.0 T is...

    We report that a transversal static magnetic field can effectively enhance glass formation of non-ferromagnetic Al-based alloys. This distinct phenomenon is mainly attributed to the Lorentz force and Joule heat generated from the magnetic field on moving alloy melts, which suppresses the...
