“…In these sensors, a Bi-substituted rare-earth iron garnet film is used as a Faraday element. In these sensors, it was clarified that the sensor output shows a large relative error in the small magnetic field region due to the small wall coercive force [2]. Hence, a new type magnetic field sensor based on creation of the Faraday effect by rotation magnetization was proposed [3].…”

In this paper, magnetic field sensors based on creation of the Faraday effect by rotation magnetization in Ce:YIG crystals are studied. The large linear magnetic birefringence (LMB) of 1 = 1 7 10 4 was observed in the Ce 0 18 Y 2 82 Fe 5 O 12 crystal and it was found from both the calculation and experimental investigations that the LMB affects the linearity of the sensor output. The validity of the method of utilizing a pair of Ce:YIG crystals with an azimuthal angle of 90 deg in the optical axis is demonstrated as a method of improving these phenomena.Index Terms-Ce:YIG single crystal, linear magnetic birefringence, magnetic field optical sensor, the Faraday effect.

The ultraviolet photoluminescence of ZnO/ZnGa 2 O 4 composite layer grown by the thermal oxidation of ZnS with gallium was investigated by the time-resolved photoluminescence as a function of measuring temperature and excitation power. With increase of excitation power, the D 0 X emission is easily saturated than the DAP emission from ZnO/ZnGa 2 O 4 composite layer, and which is dramatically enhanced as compared with that from pure ZnO layer grown without gallium. The radiative recombination process with ultra-long lifetime controlled the carrier recombination of ZnO/ZnGa 2 O 4 composite layer. C 2014 Author(s)

Microdimensional triangular magnetic antidot lattice arrays were prepared by varying the speed of substrate rotation. The pre-deposition patterning has been performed using photolithography technique followed by a post-deposition lift-off. Surface morphology taken by atomic force microscopy depicted that the growth mechanism of the grains changes from chain like formation to island structures due to the substrate rotation. Study of magnetization reversal via magneto optic Kerr effect based microscopy revealed reduction of uniaxial anisotropy and increase in domain size with substrate rotation. The relaxation measured under constant magnetic field becomes faster with rotation of the substrate during deposition. The nature of relaxation for the non-rotating sample can be described by a double exponential decay. However, the relaxation for the sample with substrate rotation is well described either by a double exponential or a Fatuzzo-Labrune like single exponential decay, which increases in applied field.
