(abstract)

The spin Peltier effect (SPE) in Pt/WSe2/Y3Fe5O12 (YIG) and Pt/WS2/YIG heterostructures is investigated using lock-in thermography. Since inserting atomically thin transition metal dichalcogenides (TMDs), such as WSe2, between Pt and YIG is known to enhance the voltage induced by the spin Seebeck effect, similar enhancement is expected for SPE. Contrary to this expectation, the SPE-induced temperature modulation is strongly suppressed in the TMD-inserted regions compared with bare Pt/YIG regions. Raman spectroscopy reveals sputtering-induced structural degradation of WSe2, hindering spin-current injection into YIG. These results highlight the sensitivity of spin-current transport to interface quality in spin-caloritronic devices incorporating atomically thin TMDs.
