A compact temperature-compensated fibre optic magnetic field sensor based on a self-referenced anti-resonant reflecting optical waveguide is proposed and experimentally demonstrated. Two hollow holes in the air ring cladding of the hollow core photonic crystal fibre (HCPCF) are infiltrated with magnetic fluid and ethanol. A self-referenced anti-resonant reflecting optical waveguide is formed in the cladding of the HCPCF between the magnetic fluid- and ethanol-infiltrated resonators. The applied magnetic field only changes the resonance condition of the magnetic fluid-infiltrated resonator, while the temperature influences the resonance conditions of both the magnetic fluid- and ethanol-infiltrated resonators simultaneously. Therefore, the proposed self-referenced anti-resonant reflecting optical waveguide can measure the magnetic field without temperature cross-sensitivity. The experimental results show that a magnetic field sensitivity of 81 pm/Oe can be achieved, and the standard variation of the wavelength difference is only 0.02 nm in the temperature range of 30 to 80 °C.
