The magnetoelastic behavior of multiferroic heterostructures—coupling of magnetic anisotropy or domain dynamics to structural deformations—has been intensively studied for developing materials for energy-efficient, spin-based applications. Here,

CoFeB/MgO-based perpendicular magnetic tunnel junctions (p-MTJ’s) with high anisotropy and low damping are critical for spin-torque transfer random access memory (STT-RAM). Most schemes of making the pinned CoFeB fully perpendicular require ferrima

Electric-field (E-field) control of magnetism enabled by multiferroic materials has the potential to revolutionize the landscape of present memory devices plagued with high energy dissipation. To date, this E-field controlled multiferroic scheme has

Magnetostrictive Co77Fe23 films are fully suspended to produce free-standing, clamped-clamped, microbeam resonators. A negative or positive shift in the resonant frequency is observed for magnetic fields applied parallel or perpendicular to the lengt

Soft magnetic Fe-B-Si-C-Cu amorphous alloys were found to exhibit simultaneously high saturation magnetization above 1.7 T, low coercivity below 5 A/m, high permeability reaching 23100 at 1 kHz and 3500 at 1 MHz as well as high Vickers hardness above

We report the in-plane magnetization reversal behavior of the Co2FeSi Heusler alloy free layer in a bottom-pinned magnetic tunnel junction film with 149% TMR. Using magneto-optic indicator film imaging, we visualize the magnetic domain dynamics of th

The influence of the magnetization configuration on the Kondo effect in a magnetic tunnel junction is investigated. In the parallel configuration, an additional resistance contribution ( R ⁎ ) below 40 K exhibits a logarithmic temperature dependenc
