Room Temperature Skyrmions in Pt/Co/Ta multilayers
Room Temperature Skyrmions in Pt/Co/Ta multilayers
Magnetic skyrmions are topologically stabilized spin configurations on the nanoscale. In magnetic multilayers, they can be stabilized at room temperature. Polycrystalline[Pt(40Å)/Co(x)/Ta(19Å)$_N$ multilayers were fabricated in a molecular beam epitaxy setup by thermal deposition on oxidized Si(001)...

Magnetic skyrmions are topologically stabilized spin configurations on the nanoscale. In magnetic multilayers, they can be stabilized at room temperature. Polycrystalline[Pt(40Å)/Co(x)/Ta(19Å)$_N$ multilayers were fabricated in a molecular beam epitaxy setup by thermal deposition on oxidized Si(001) substrates with a Ta buffer layer and a Pt cap layer. The Co film thickness was varied between 5 Å and 21 Å and N varied between 8 and 10.Magnetic force microscopy measurements reveal the existence of skyrmions at a Co thickness between 9 Å and 17 Å. We discuss results obtained from magnetic hysteresis, transport and neutron reflectome- try measurements. The latter have been performed with the neutron reflectometer Platypus at ANSTO, Australia. |
