Automated mechanical exfoliation method: a spin pumping research in YIG/TMD heterostructures

[ad_1]

Spintronics gadgets depend on the era and manipulation of spin currents. Two-dimensional transition-metal dichalcogenides (TMDs) are among the many most promising supplies for a spin present era resulting from an absence of inversion symmetry on the interface with the magnetic materials. Right here, we report on the fabrication of Yttrium Iron Garnet(YIG)/TMD heterostructures by the use of a crude and quick technique. Whereas the magnetic insulator single-crystalline YIG skinny movies have been grown by magnetron sputtering, the TMDs, specifically MoS2 and MoSe2, have been instantly deposited onto YIG movies utilizing an automatic mechanical abrasion technique. Regardless of the brute drive facet of the strategy, it produces high-quality interfaces, that are appropriate for spintronic machine purposes. The spin present density and the efficient spin mixing conductance have been measured by ferromagnetic resonance, whose values discovered are among the many highest reported within the literature. Our technique may be scaled to supply ferromagnetic supplies/TMD heterostructures on a big scale, additional advancing their potential for sensible purposes.
