The occurrence of oscillations in the transverse magnetic field confirms the ... An oscillation in the conductivity of a material that occurs at low temperatures in the presence of very intense magnetic fields, the Shubnikov–de Haas effect (SdH) is a macroscopic manifestation of the inherent quantum mechanical nature of matter. It is often used to determine the effective mass of charge carriers (electrons and electron holes), allowing investigators to distinguish among majority and minority carrier populations. The effect is named after Wander Johannes de Haas and Lev … WebDec 1, 2024 · The Shubnikov-de Haas (SdH) oscillation amplitude increased by 30% while oscillation frequencies remained the same.
