概要
- 論文の詳細を見る
The magnetic response of ErBa_2Cu_3O_<6+x> has been studied in terms of complex susceptibility χ=χ'-iχ". Our previous work suggested that the superconductivity of ErBa_2Cu_3O_<6+x> consists of bulk and weakly-coupled phases. We pulverized the pellet to depress the superconductive couplings in the specimen. The ac susceptibility data well reflect a bulk superconductive nature: χ' is insensitive to the field amplitude and χ" does not show any change in the transition region, giving sound confirmation of our previous explanation.
