The Hall Electric Field in Earth's Magnetotail Thin Current Sheet

Lu, San; Artemyev, A., V; Angelopoulos, V; Lin, Y; Zhang, X-J; Liu, J.; Avanov, L.A.; Giles, B. L.; Russell, C. T.; Strangeway, R. J. (2020-05-28)

One of the most important properties of Earth's magnetotail thin current sheet (TCS) is that its current is predominantly contributed by magnetized electrons. The Hall electric field, normal to the TCS and generated by ...
