摘要: A polarization plane switch comprising a Faraday rotator made of an iron-containing garnet single-crystal film and magnetic field applying devices capable of reversing a magnetic field to be applied to the Faraday rotator. The polarization plane switch has a structure in which magnetization of part of the Faraday rotator is unsaturated and that of the remaining portion of it is saturated when a magnetic field is applied to the Faraday rotator by the magnetic field applying device, and a light beam passes through the magnetically saturated portion almost vertically to the film surface. As the above Faraday rotator, it is the most preferable to use a Faraday rotator made of Bi-substituted iron garnet single crystal formed by liquid-phase epitaxy and having a compensation temperature, and thermally treated under the top condition at a temperature between 1,120.degree. and 1,180.degree. C. for 7 hours or less.

摘要: A low temperature sinterable oxide magnetic material prepared by adding 0.1 to 5% by weight of glass containing 3 to 50 mol % of Li.sub.2 O, 10 to 97 mol % of B.sub.2 O.sub.3 and 0 to 70 mol % of SiO.sub.2 to ferrite containing at least 0.5 mol % of Li.sub.2 O. Especially, when a glass containing 10-28 mol % of Li.sub.2 O, 34 to 66 mol % of B.sub.2 O.sub.3, and 15 to 45 mol % of SiO.sub.2 is used, the sintering temperature can be reduced to about 1,000.degree. C. or less.
