英文摘要
We have examined effect of applied magnetic field on magnetic domains of Co-Ho and Co-Pt thin films using magnetic fields generated by objective lens or mini condenser lens of a transmission electron microscope. For this purpose, we employed a single-axis specimen tilt holder, which is high tilt angle compatible for electron tomography. We obtained following results in situ using the Fresnel mode: (1) magnetic domains in a Co-17at%Ho thin film grow via domain wall movement when magnetic field is applied, and (2) magnetic contrast inside a Co-27at%Pt particle changes when the magnetic field direction changes.
