Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

Early in the study of electronics we are introduced to magnetism. The lines of force can be demonstrated by iron filings on a sheet of paper with a magnet underneath. In school science class, we made ...

Coexistence of chiral DW and QAHE can be achieved in QAH insulators with sizable Dzyaloshinskii–Moriya interactions. Domain walls act as natural boundaries separating edge states with opposite ...
