【摘要】 本文研究了一种铝硼硅酸盐基质玻璃,通过加大单位体积的稀土离子浓度,并选择P值大的顺磁性Tb³⁺作为弗尔德常数贡献的主要离子,经反复试验研究,制定合理的熔制工艺,得到性能稳定的透明顺磁旋光玻璃。弗尔德常数V=-0.375/Oe·cm。是目前世界上弗尔德常数较高的磁旋光玻璃。更多还原

【Abstract】 A special aluminum borosilicate glass has been developed to increase concentration of rare-earth ions per unit volume, Choosing large p value of Tb3+ ion, and using our extraordinary fusing technique, an excellent Tb aluminum borosilicate glass has. been fabricated. Verdet constant V of the glass is higher as - 0.375min/Oe.cm and is believed better than present FR type magneto-optical glasses.更多还原
