Development of selection system for levitated nano-particle using photo-thermal effect

本文介绍了光驱动方法在抗磁性材料中的应用数值分析和实验。该系统由永磁体、热敏铁氧体和光源组成。由于抗磁性材料可以被动悬浮，因此可以在无接触的情况下有效驱动。温敏铁氧体的磁化率取决于光热效应控制的温度。热敏铁氧体加热后磁通分布发生变化。因此可以无接触地控制抗磁性材料。从一维和三维数值分析出发，推导了抗磁材料非接触光驱动的可能性。因此，成功地控制了反磁性材料，而不是光使用烙铁。

This application is described light-driven method for diamagnetic material in numerical analysis and experiments. The proposed system consists of permanent magnets, temperature-sensitive ferrite and light source. Since diamagnetic material can levitate passively, it was driven efficiently without contact. Magnetic susceptibility of temperature-sensitive ferrite depends on its temperature controlled by photo-thermal effect. Magnetic flux distribution changes by heating temperature-sensitive ferrite. Therefore diamagnetic material can be control without contact. Noncontact light-driving possibility of diamagnetic material is derived from numerical analysis in one and three dimension. As a result, diamagnetic material is successfully controlled by using soldering iron instead of light.
