A carbon coil was evaluated for use as a micro-solenoid in a small magnetic device. A single carbon coil was lifted out of the aggregate using a tungsten fine probe in a focused ion beam (FIB) system and was wired to two small electrodes in the specimen holder of a transmission electron microscope (TEM). A direct current was supplied to the single carbon coil. A micro/nano-magnetic field generated from the coil was directly observed by electron holography. A computer simulation of electron holography was also done to quantitatively analyze the magnetic field. Details on the FIB technique, the electron holographic observation and the simulation are described.
对一种碳线圈进行了评估,以确定其在小型磁性装置中用作微螺线管的可行性。在聚焦离子束(FIB)系统中,用钨微探针从聚集体中取出单个碳线圈,并将其连接到透射电子显微镜(TEM)样品架中的两个小电极上。向单个碳线圈施加直流电。通过电子全息术直接观察到线圈产生的微/纳米磁场。还进行了电子全息术的计算机模拟,以定量分析磁场。文中描述了FIB技术、电子全息观察和模拟的详细信息。
