论文摘要
我们通过在应用可变的磁性梯度时测量物质波纹条纹的去量来探索广泛的基本磁现象。我们的干涉式船尾技术的多功能性使我们能够在同一设备中研究碱原子,有机自由基和富勒烯,磁矩从Bohr Magneton到小于核Magneton不等。我们发现有机自由基超音速束的磁化证据,最值得注意的是,观察到热C $ _ {60} $束的强磁反应与高温原子样旋转磁矩的偏转一致。
We explore a wide range of fundamental magnetic phenomena by measuring the dephasing of matter-wave interference fringes upon application of a variable magnetic gradient. The versatility of our interferometric Stern-Gerlach technique enables us to study alkali atoms, organic radicals and fullerenes in the same device, with magnetic moments ranging from a Bohr magneton to less than a nuclear magneton. We find evidence for magnetization of a supersonic beam of organic radicals and, most notably, observe a strong magnetic response of a thermal C$_{60}$ beam consistent with high-temperature atom-like deflection of rotational magnetic moments.
