Fission of longitudinal autosolitons in InSb in a magnetic field

The behavior of longitudinal autosolitons in InSb in a weak magnetic field was studied. It is shown experimentally that a weak longitudinal magnetic f ield affects significantly the behavior of longitudinal autosoliton in InSb samples. In all samples, sharp changes in the current due to fission of lo ngitudinal autosoliton were observed for certain values of a magnetic field . It was found that the magnitude of initial autosoliton current took a dif ferent stable value under the effect of a magnetic field. The initial value of the autosoliton current is recovered if a magnetic field of opposite or ientation is applied to the sample. (C) 2000 MAIK "Nauka/Interperiodica".
