Effect of Magnetic and Nonmagnetic Layers Parameters on Dissipation Processes in Multilayer Nanostructures with Antiferromagnetic Component
The experimental research of magnetic relaxation in multilayer nanostructures AFM/Cu/FM (AFM Mn80Ir20 – antiferromagnet, FM Ni80Fe20 – ferromagnetic) with different thicknesses of the magnetic and non-magnetic (Cu) layers were done in this work. Samples were prepared by magnetron sputtering. The...

| description | The experimental research of magnetic relaxation in multilayer nanostructures AFM/Cu/FM (AFM Mn80Ir20 – antiferromagnet, FM Ni80Fe20 – ferromagnetic) with different thicknesses of the magnetic and non-magnetic (Cu) layers were done in this work. Samples were prepared by magnetron sputtering. The effects of the spin pumping in system FM/AFM were observed with the use of ferromagnetic resonance (FMR), namely, on broadening of FMR line. As a result of the work the magnetic parameters of samples, including the value of the magnetization and uniaxial anisotropy were found. By analyzing the experimental data and conducting the simulation the contribution to setting of the magnetization attenuation caused by spin pumping effect (sp) for each series sample was found. It was established that the value sp affects the thickness of the magnetic and (in some cases) nonmagnetic layers. Obtained results are useful for further study of dissipative effects in spintronic devices based on antiferromagnets. |
