Tunneling and magnetotunneling properties of GaAs-based p-type double barrier resonant tunneling diodes (RTD's) with a ferromagnetic (Ga,Mn)As emitter layer are studied. Current-voltage characteristics of RTD's revealed the presence of spontaneous magnetization in the (Ga,Mn)As emitter. The transverse magnetic field results suggest that the valence band dispersion of (Ga,Mn)As is different from GaAs.
