超导体可以捕获大的磁场。然而，垂直于俘获场的磁场降低了俘获场的有效性，这被称为交叉场退磁。交叉磁场退磁成为叠层磁体应用中的一个难题。研究了具有大临界电流密度的尤巴包覆BaHfO3纳米棒导体的交叉场退磁。磁化后再加横向交流磁场，陷获场的衰减速度明显加快。然而，对于小于平行于ab平面的全穿透场的AC场，衰减变得足够慢。所有这些结果表明，如果交变横向磁场降低到穿透磁场以下，我们可以将堆叠磁体应用于旋转电机。
Superconductors can trap large magnetic fields. However, magnetic fields perpendicular to the trapped field reduces the trapped field effective, which is known as crossed-field demagnetization. Crossed-field demagnetization becomes a problem for the application of stacked magnet. We investigated the crossed-field demagnetization of a EuBa 2 Cu 3 O 7 coated conductor with BaHfO 3 nonorods which has large critical current density. When an AC transverse field is applied after the magnetization of the coated conductor, the decay of trapped field was significantly accelerated. However, for the AC field smaller than the full penetration field parallel to the ab-plane, the decay becomes slow enough. All these results suggests that we can apply the stacked magnet for rotating machines if the alternating transverse magnetic field is reduced below the penetration field.
