日本三菱电线工业公司开发成功了采用溶胶法制造钇—钡—铜等具有优良特性的高温超导薄膜。这种膜的厚度为3～4微米的高温超导薄膜具有如下特性,当临界温度为88K 以上时,其临界电流密度达6700A/cm~2以上。溶胶法由于不需要像飞溅涂膜法和蒸镀法那样的真
Japan’s Mitsubishi Cable Industries has successfully developed the use of sol method yttrium - barium - copper and other excellent characteristics of the high temperature superconducting thin film. The high-temperature superconducting thin film with the thickness of 3 to 4 microns has the following characteristics. When the critical temperature is above 88K, the critical current density reaches 6700A / cm ~ 2 or more. The sol method does not require realism like the splash coating method and the vapor deposition method
