Current oscillations in the negative differential conductance region of resonant tunneling diodes with different lateral pattern and size versus perpendicular to the tunneling current magnetic field have been studied. It is revealed that the value of the critical negative differential conductance or oscillations threshold that is the value of conductance when the oscillations in measurement circuit are arisen, unmonotonically depends on magnetic field. The relation of the observed dependence with inhomogeneous distribution of the tunneling current is discussed.
