“…The Faraday rotation spectrum exhibited a peak between 500 and 550 nm owing to bismuth substitution, which is in agreement with previous reports. 26,28) In our study, the maximum Faraday rotation angle reached 11 deg. at a wavelength of 530 nm.…”

“…To overcome this problem, we have succeeded in preparing highly Bi-substituted neodymium iron garnet (Nd 3−x Bi x Fe 5−y Ga y O 12 ) films on glass and GGG substrates by the metal-organic decomposition (MOD) method. [24][25][26][27][28][29][30][31][32] Considering the large-scale measurement of MO images, we need to develop a novel optical system, because the conventional setup used for the Kerr microscope is not applicable for large-scale imaging. If we use the same concept of the conventional setup for a large-scale imaging, large lenses and mirrors are required to obtain a sufficient polarization property for MO imaging, which will be too large for practical use.…”

We develop a light source, a polarizing film, and a highly bismuth-substituted neodymium iron garnet film which exhibits a large Faraday rotation angle of 11 deg., prepared on a ϕ150 mm diameter glass substrate by the metal-organic decomposition method. To measure the magnetic field distribution quantitatively, the 45°polarizer method was carried out. The magnetic field distribution of a bar magnet was quantitatively measured. Furthermore, we also carried out the polarization modulation method using a white light for quantitative magneto-optical (MO) imaging.

Magneto-optical (MO) imaging using MO imaging plates is a magnetic imaging technique that enables real-time measurements and is expected to be used for non-destructive testing and for observing the magnetic domains of magnetic materials. In this study, we propose a quantitative measurement method for three dimensional (3D) magnetic field vector measurements. The x-and y-components of the magnetic fields within the measured plane are calculated from the measured z-component by using a signal transformation method based on magnetic field transfer functions. Furthermore, the magnetic field distributions at different heights are also obtained from a one-shot image. In this paper, 3D magnetic field vector measurements are demonstrated for ferrite magnets and an electrical steel sheet.

“…However, it is difficult to achieve a high Bi substitution, and the size of films is limited by that of the single crystal substrate such as Gd3Ga5O12 (GGG), which is typically smaller than 4 inches in diameter 12)-14) . To overcome these problems, we prepared highly Bi-substituted neodymium iron garnet (Nd3-xBixFe5-yGayO12) films, by metal-organic decomposition (MOD) on glass and GGG substrates 15) . This allows larger MO imaging plates to be prepared.…”

We propose a magneto-optical (MO) color imaging technique that enables magnetic field distributions to be quantitatively observed in real-time. Values of magnetic fields are displayed as colors. MO imaging plates have been developed using highly bismuth-substituted neodymium iron garnet films, for use in MO color imaging. The films were prepared by the metal-organic decomposition method. The MO imaging plates were characterized using the MO figure of merit for MO imaging plates, which is defined in this study. The magnetic fields were expressed by colors, using light-emitting diodes (LEDs) as light sources. The colors varied from blue to yellow, from green to yellow, and from blue to red, for sources corresponding to a white LED, combined green and yellow LEDs, and combined blue and yellow LEDs, respectively. The MO color imaging of spherical magnets is demonstrated.Key words: magneto-optical imaging, bismuth substituted neodymium iron garnet, magneto-optical effect, metal organic decomposition, magneto-optical imaging plate, magneto-optical figure of merit
