Transparent ceramic for magneto-optical element, and magneto-optical element
The present invention relates to a transparent ceramic for a magneto-optical element, comprising: a paramagnetic garnet-type composite oxide containing terbium, lutetium, and aluminum represented by formula (1); and 100 to 1000 ppm by mass of Si as a sintering aid. (Tb1-xLux) 3Al5O12... (1), wherein x is greater than or equal to 0.05 and less than or equal to 0.45. The magneto-optical element of the present invention is an optical isolator which comprises a transparent ceramic for magneto-optical elements as a Faraday rotor (110), and a polarizer (120) and an analyzer (130) in front of and behind the Faraday rotor on an optical axis (102), and which can be used in the wavelength range of 0.9 to 1.1 [mu] m.
本发明涉及一种磁光学元件用透明陶瓷，其包含：下列式(1)所示的含有铽、镥和铝的顺磁性石榴石型复合氧化物，以及作为烧结助剂的100质量ppm至1000质量ppm的Si。(Tb1‑xLux)3Al5O12……(1)，式中0.05≤x≤0.45。本发明的磁光学元件是光隔离器，其包括作为法拉第转子(110)的磁光学元件用透明陶瓷以及在光学轴(102)上的法拉第转子前后的偏振器(120)和检偏器(130)，并且其可以在0.9至1.1μm的波长范围使用。
