We describe the design, assembly, and testing of a magnet intended to deflect beams of paramagnetic nanoclusters, molecules, and atoms. It is energized by high-grade permanent neodymium magnets. This offers a convenient option in terms of cost, portability, and scalability of the construction while providing field and gradient values (1.1 T, 330 T/m), which are fully comparable with those of commonly used electromagnet deflectors.

用于分子束 Stern-Gerlach 型实验的强永磁梯度偏转器

我们描述了旨在偏转顺磁性纳米团簇、分子和原子束的磁铁的设计、组装和测试。它由高级永磁钕磁铁供电。这在成本、便携性和结构可扩展性方面提供了一个方便的选择，同时提供了与常用电磁偏转器完全可比的场和梯度值（1.1 T，330 T/m）。
