To provide a novel superconducting bulk magnet device which is capable of generating a magnetic field larger than an applied magnet field and capable of persistently generating a magnetic field larger than an applied magnet field even after the applied magnetic field is zeroed.SOLUTION: A hybrid-type superconducting bulk magnet device is configured such that: a bulk superconductor magnetic lens 12 having a shape to focus a magnetic field and having different characteristics from a cylindrical bulk superconductor 13 is disposed in the inner center of the cylindrical bulk superconductor 13; by magnetizing the cylindrical bulk superconductor 13 by a superconducting magnet 14 for magnetization installed at the outside, a capturing phenomenon of a magnetic field by the cylindrical bulk superconductor 13 is combined with a magnetic convergence effect by the bulk superconductor magnetic lens 12; a magnetic field larger than an applied magnetic field is generated; and, even after magnetic field application by the superconducting magnet 14 for magnetization is zeroed, a magnetic field larger than an applied magnetic field can be persistently generated.SELECTED DRAWING: Figure 2【課題】印加磁場より大きな磁場を発生でき、しかも、印加磁場をゼロにした後も、印加磁場より大きな磁場を持続的に発生することができる新規な超電導バルク磁石装置を提供する。【解決手段】円筒状バルク超電導体13の内部中心に、磁場を収束させるための形状を有する円筒状バルク超電導体13とは異なる特性のバルク超電導体磁気レンズ12を配置し、外部に設置した着磁用超電導マグネット14により円筒状バルク超電導体13を着磁することにより、円筒状バルク超電導体13による磁場の捕捉現象と、バルク超電導体磁気レンズ12による磁気収束効果を組み合わせ、印加磁場より大きな磁場を発生させ、かつ、着磁用超電導マグネット14による磁場印加をゼロにした後も印加磁場より大きな磁場を持続的に発生できるようにする。【選択図】図2
