Measuring the temperature of the spin via weak measurement

Yusuf Turek

Figure 1. The setup of our scheme. A spin with temperature T in large reservoir and the cantilever are coupled with each other by the magnetic field of the tiny ferromagnetic particle attached to the middle of the cantilever. d is the distance between the bottom of the ferromagnetic particle and the spin at the equilibrium position, z = 0. The spin is also exposed to the transversal frequency modulated rf magnetic field in x − y plane.
