Abstract: PURPOSE:To detect highly accurately the existence of a magnetic field in a narrow space by using a bismuth substitutional magnetic garnet monocrystal film in which the [111] axis of a Faraday rotor is inclined within range of a specific angle to a normal of the film. CONSTITUTION:An optical magnetic field sensor head is formed by arranging a light input and output passage 23 of optical fiber, a polarizer 20 of a polar core, a bismuth substitutional magnetic garnet monocrystal film (Faraday rotor) 21 having a specific multiple magnetic domain structure [111] and a reflecting film 22 of a gold thin film in order. Here, in the monocrystal film 21, the [111] axis is inclined within a range of about 5-60 deg. from a normal of the film. This is installed instead of a magnetic field sensor head of a reflection type photomagnetic field sensor. When impression of a magnetic field of the photomagnetic field sensor head is changed, signal light of a light source 1 passes through a half mirror 3, the input and output passage 23, the polarizer 20 and the rotor 21, and is reflected by the reflecting film 22, and passes through an inverse optical path, and changes the optical path by the mirror 3, and a light detector 8 measures the light intensity. That is, a small and lightweight reflection type photomagnetic field sensor head capable of detecting the existence of the magnetic field in a narrow space, can be obtained by using a magneto-optical material having the multiple magnetic domain structure as the Faraday rotor.
