我们已经成功地利用应变驱动的自卷绕技术制造了微米尺寸的三维手性钴元分子（CMM）阵列。在阵列中，Co三坐标测量机固定在硅衬底上并沿同一方向排列。我们研究了在不同角度的外部直流磁场作用下阵列的铁磁共振。Co三坐标测量机阵列显示各向同性共振信号，其共振场与直流场相对于螺旋轴的方向无关。
We have succeeded in fabricating arrays of micrometer-sized, three-dimensional chiral meta-molecule (CMM) of cobalt (Co) by using a strain-driven self-coiling technique. In the arrays, the Co CMMs were fixed on a silicon substrate and aligned in the same direction. We investigated the ferromagnetic resonance of the arrays with varying angles of an external dc magnetic field. The Co CMM arrays show isotropic resonance signals, whose resonance fields are independent of the dc field orientation with respect to the helical axis.
