(PDF) Spin-orbit torque from a ferromagnetic metal.
Feb 13, 2020 · Spin current generated in a ferromagnetic metal (FM) can be divided into two types. While one is magnetization dependent and induced by the well-known anomalous Hall effect, the other is a magnetization-independent spin Hall effect which is similar to that in a paramagnetic heavy metal (HM). Here, we study the magnetization-independent spin Hall current in YIG/FM (NiFe and CoFeB) via spin.

Unlike ferromagnetism, anti-ferromagnetic interactions can lead to multiple optimal states (ground states—states of minimal energy). In one dimension, the anti-ferromagnetic ground state is an alternating series of spins: up, down, up, down, etc. Yet in two dimensions, multiple ground states can occur. The inverse spin Hall effect (ISHE) has been observed only in nonmagnetic metals, such as Pt and Au, with a strong spin-orbit coupling. We report the observation of ISHE in a ferromagnetic permalloy (Py) on ferromagnetic insulator yttrium iron garnet (YIG). Through controlling the spin current injection by altering the Py-YIG interface, we have isolated the spin current contribution and.

1 day ago · In summary, we have successfully demonstrated the effect of paramagnetic metal ion incorporation in a highly rigid supramolecular structure. Magnetic-structural studies have confirmed the intra and interchain interactions inducing spin canting and long-range ferromagnetic ordering at low temperatures. Domains of different sizes are common in ferromagnetic materials. Every domain's spin magnetic moments are normally aligned parallel to one another. Ferrimagnetic materials are similar to anti-ferromagnetic materials, but one set of spins is not equal to the magnitude of the other set of spins (say opposite spins).

Abstract. The magnetoresistance of ferromagnetic metals due to spin fluctuation through s-d interaction is calculated for the whole temperature region and for the weak magnetic field. The ladder approximation (RPA) is used in the calculation of the spin Green's functions and it is shown that the magnetoresistance has a logarithmic dependence on the temperature and the magnetic field both at. Such anomalous Dresselhaus-like spin current is further confirmed by the current-induced shift of the hysteresis loop when the magnetic field is swept along the current direction. However, when the ferromagnetic metal exhibits amorphous crystal structure or polycrystal structure, the Dresselhaus-like spin current is absent. Jul 13, 2005 · Simple pictorial models of spin waves are introduced.
