Orthoferrite sind transparente Magnetwerkstoffe, die durch eine Vielzahl einzigartiger Eigenschaften (sehr hohe magnetooptische Gª und Qualit~itsfaktor, extrem hohe Dom~inenwandgeschwindigkeit) charakterisiert sind. Ihre Einsatzm6glichkei-ten in innovativen mikrotechnologischen Vorrichtungen mit verbesserten Eigenschaften sind sehr vielversprechend. In dieser Arbeit werden Anwendungen von Orthoferriten zur Messung von elektrischen Str6men (Magnetfeldern) und Winkelmessungen sowie Anwendungen fª die Entwicklung neuer Typen optischer Elemente, wie Trenner, Schalter und Schlief5er, pr~isentiert. Schlª magneto-optische Sensoren; Faraday-Effekt; OrthoferriteApplications oftransparent magnets. Orthoferrites are transparent magnetic materials characterized by a number of unique features (very high values of magneto-optical figure of merit and quality factor, extremely high domain wall velocities) promising their use for the developement of various innovative micotechnological devices with improved characteristics. A review of applications in electric current (magnetic field) meters, angle measuring devices, optical modulators, switches, shutters, and isolators will be presented.

“…Current can be measured by detecting magnetic field around the current cable. At present most research is based on bulk magnetostrictive materials [1] and magneto-optical crystal [2], there are rarely investigations using SPFBG dipped in magnetic fluid as sensing element. It is reported that long-period fiber grating (LPFG) has a high wavelength shift [3] when immersed with magnetic fluid.…”

A novel optical fiber magnetic sensor based on magnetic fluid is proposed in this paper. Stable nano-particle CoFe 2 O 4 magnetic fluid was synthesized firstly; the CoFe 2 O 4 magnetic fluid was injected in capillaries containing side-polished fiber Bragg grating (SPFBG) as sensing element. The reflected Bragg wavelength was changed by varying the magnetic field which is perpendicular to the axial of SPFBG. Magnetic field sensing experiment show that 35pm of wavelength shift at a magnetic field intensity of 16mT.
