We have performed magneto‐tunneling experiments from three‐dimensional electrodes through self‐assembled InAs quantum dots. Our measurements show magnetic‐field‐induced Fermi edge singularities which are strongly enhanced in high magnetic fields. Electrons carrying the majority spin in the emitter show the most pronounced singularities. We compare our experimental results with theoretical calculations.
