Electric-field-induced magnetization reversal in a ferromagnet-multiferroic heterostructure.
A reversal of magnetization requiring only the application of an electric field can lead to low-power spintronic devices by eliminating conventional magnetic switching methods. Here we show a nonvolatile, room temperature magnetization reversal determined by an electric field in a ferromagnet-multiferroic system. The effect is reversible and mediated by an interfacial magnetic coupling dictated...
متن کاملFast 180° magnetization switching in a strain-mediated multiferroic heterostructure driven by a voltage
Voltage-driven 180° magnetization switching provides a low-power alternative to current-driven magnetization switching widely used in spintronic devices. Here we computationally demonstrate a promising route to achieve voltage-driven in-plane 180° magnetization switching in a strain-mediated multiferroic heterostructure (e.g., a heterostructure consisting of an amorphous, slightly elliptical Co...
متن کاملOrigin of electric-field-induced magnetization in multiferroic HoMnO3.
We have performed polarized and unpolarized small angle neutron scattering experiments on single crystals of HoMnO(3) and have found that an increase in magnetic scattering at low momentum transfers begins upon cooling through temperatures close to the spin reorientation transition at T(SR) approximately 40 K. We attribute the increase to an uncompensated magnetization arising within antiferrom...
متن کاملLaser-induced magnetization dynamics in a cobalt/garnet heterostructure
We report on magnetization dynamics triggered in a Co/garnet heterostructure by femtosecond laser pulses. Although laser excitation of a bare Co-doped yttrium iron garnet leads to magnetization precession, the phase of which strongly depends on the linear polarization of the light pulses, the deposition of an ultrathin Co layer on a top of a garnet film results in substantial changes of the las...
متن کاملCupric oxide as an induced-multiferroic with high-TC.
Materials that combine coupled electric and magnetic dipole order are termed 'magnetoelectric multiferroics'. In the past few years, a new class of such materials, 'induced-multiferroics', has been discovered, wherein non-collinear spiral magnetic order breaks inversion symmetry, thus inducing ferroelectricity. Spiral magnetic order often arises from the existence of competing magnetic interact...
