The magnetic domain structure of magnetic single crystals depends on crystal quality and crystal orientation, and by observing and clarifying the domain structure, one can evaluate the single-crystalline quality of the sample. When using YIG single crystals as materials for quantum computers, suppressing crystal defects and accurately determining the single-crystal orientation play crucial roles. Therefore, in this study, we developed a new polarizing microscope and conducted magnetic domain observations of YIG single crystals; the results are reported.
