WebbThe starting point of the Bloch-Redfield formalism is the total Hamiltonian for the system and the environment (bath): H = HS + HB + HI, where H is the total system+bath Hamiltonian, HS and HB are the system and bath Hamiltonians, respectively, and HI is the interaction Hamiltonian. WebbThanks to the excellent magneto-optical characteristics of the MF, the proposed sensor can achieve a magnetic field intensity sensitivity of 44.69 nm/mT in the range of 3-7.4 mT. The minimum magnetic field intensity can be detected is 0.45 μT due to the 0.02 nm wavelength resolution of the optical spectrum analyzer.
