Magnetic field optical sensors using Ce:YIG single crystals as a Faraday element

Preparation of nano-sized Al-substituted yttrium iron garnets by the mechanochemical method and investigation of their magnetic properties

“…This corresponds to the moment of the one Fe 3+ ion which is present in a tetrahedral site in number more than Fe 3+ ions in an octahedral site [7]. YIGs are also of scientific importance because of the wide variety of magnetic properties that we can obtain substituting Y by rare earth metals [8][9][10][11][12][13] or substituting Fe by other trivalent cations [14][15][16][17]. For instance, Zhao et al [18] have demonstrated that bi-substitution can effectively reduce the relative dielectric constant and loss tangent of YIG.…”

Review on optical fiber sensors with sensitive thin films

“…Current can be measured by detecting magnetic field around the current cable. At present most researches are based on bulk magnetostrictive materials [36][37][38] and magneto-optical crystal [39][40][41], and there are rarely investigations using FBG dipped in the magnetic fluid as sensing element. It was reported that long-period fiber grating (LPFG) had a high wavelength shift [42] when immersed in the magnetic fluid.…”

Study on a multifunctional crystal LiMnBO3

“…As typical magneticoptical materials, Yttrium iron garnet (Y 3 Fe 5 O 12 , YIG) and doped-YIG have been widely applied in tunable microwave devices, circulators, isolators, phase shifters, nonlinear devices, etc. [3,4]. Lithium niobate (LiNbO 3 ) and lithium tantalite (LiTaO 3 ) have found significant applications that exploit their electro-optic characteristic, such as electro-optic modulation [5,6].…”
