Simulation results of the thermal relaxation. a Schematic diagram of the experimental situation. The heat supplied to the spin system first flows to the lattice system through the thermal conductance, KSL, and then to the heat bath through KB. PS (PL) and CS (CL) represent the heating power of the spin (lattice) heating and the heat capacity of the spin (lattice) system, respectively. TS, TL, and TB denote the temperature of the spins, lattice, and bath, respectively. b The thermal relaxation curve when the spins are strongly coupled to the lattice [ΔTS(t) = TS(t) − TB and ΔTL(t) = TL(t) − TB]. The thermal relaxation curve when the spins are decoupled from the lattice for c the lattice heating and d the spin heating. Inset of d: the enlarged figure of the main panel. Magenta and cyan lines represent ΔTS(t) and ΔTL(t), respectively
