Abstract

Abstract: In this study, we show the real-space observation of the magnetic domain configuration in amorphous Ce14 Fe80 B6 ribbon using Lorentz transmission electron microscopy. Cross-tie domain walls composed of magnetic vortices (Vs) and antivortices (AVs) are observed. The evolution of Vs/AVs manipulated by temperature, in-plane magnetic field, and electrical current is clearly demonstrated. Magnetic V nucleation and annihilation in pair are observed because of the stimulus of external fields. Graphical abstract: Image
