چکیده
We investigate the coupled magnetization dynamics in heterostructures of a single crystal chiral magnet [Formula: see text] (CSO) and polycrystalline ferromagnet (Py) thin film using broadband ferromagnetic resonance (FMR) at cryogenic temperatures. observe excitation hybrid mode (HM) below helimagnetic transition temperature CSO. This HM is attributed to spin CSO/Py interface. study by measuring its frequencies for plane rotations external magnetic field. find that exhibits dominantly fourfold anisotropy contrast FMR CSO Py.

متن کاملNonlocal magnetization dynamics in ferromagnetic hybrid nanostructures
Two complementary effects modify the GHz magnetization dynamics of nanoscale hybrid structures of ferromagnetic and normal materials from those of the isolated magnetic constituents: On the one hand, a time-dependent ferromagnetic magnetization pumps a spin angular-momentum flow into adjacent materials and, on the other hand, spin angular momentum is transferred between ferromagnets by an appli...
متن کاملOrigin of spontaneous magnetization reversal in exchange biased heterostructures
The dependence of thermally induced spontaneous magnetization reversal on time-dependent cooling protocols implies that this reversal is energetically favored, contrary to the prediction of existing positive exchange bias models. Slow cooling through and long waiting near the Néel temperature of the antiferromagnet enhances the magnitude of the magnetization reversal. Further, cycling the tempe...

Magnetization Dynamics in Racetrack Memory Various devices have been proposed which use magnetic domain walls (DWs) in nano-sized magnetic structures to perform logic operations or store information. In particularin ‘Racetrack memory’ bits of information represented by DWs are shifted in amagnetic wire to be stored. For these memory and logic devices to be successful, greatcontr...
متن کاملChiral superfluid States in hybrid graphene heterostructures.
We study the "hybrid" heterostructure formed by one sheet of single-layer graphene (SLG) and one sheet of bilayer graphene (BLG) separated by a thin film of dielectric material. In general, it is expected that interlayer interactions can drive the system to a spontaneously broken-symmetry state characterized by interlayer phase coherence. The peculiarity of the SLG-BLG heterostructure is that t...
