The transition metal dichalcogenide 1T-TaS2 is known to exhibit a number of collective electronic states known as charge density wave (CDW) instabilities. Intriguing phenomena such as a large damping-like spinorbit torque (SOT) have been reported in monolayer 1T-TaS2 [Nano Lett.2020, 20 (9), 6372–6380]. Probing of CDWs in monolayer thick 1T-TaS2 has been an inconceivable task. Here, the temperature-dependent spin dynamics and the effect of CDWs in the 1T-TaS2(monolayer)/Ni81Fe19 (Py) (7 nm) heterostructure are reported. Employing ferromagnetic resonance, the effect of the different commensurate (C) and nearly commensurate (NC) CDW states on the spin dynamics during heating and cooling cycles has been characterized by use of the effective damping constant and the spin mixing conductance of the heterostructure.
