论文摘要
我们提出了一项研究，研究使用交替的磁场捕获硬铁磁颗粒，重点是平面陷阱几何形状。首先，我们意识到并表征了基于旋转磁力电位的毫米大小的磁性保罗陷阱设计。我们使用两对具有相反极杆的永久磁体的物理旋转平台，在陷阱上方有一厘米的硬铁磁捕获稳定的捕获，并证明粒子形状在捕获中起着至关重要的作用。最后，我们提出了一种芯片陷阱设计，该设计将为使用铁磁性微粒的研究开辟一条研究。
We present a study on the trapping of hard ferromagnetic particles using alternating magnetic fields, with a focus on planar trap geometries. First, we realize and characterize a magnetic Paul trap design for millimeter-size magnets based on a rotating magnetic potential. Employing a physically rotating platform with two pairs of permanent magnets with opposite poles, we show stable trapping of hard ferromagnets a centimeter above the trap and demonstrate that the particle shape plays a critical role in the trapping. Finally, we propose a chip trap design that will open a path to studies of gyromagnetic effects with ferromagnetic micro-particles.
