was observed in magnetic fields with induction up to 10 T at temperature range 4.2-70 K. The effect was explained taking into account two-channel conductivity of the whiskers with core-shell structure. Besides, the obtained results were discussed in the framework of the quantum magnetoresistance theory. The obtained results allow to design the magnetic field sensor on the deformed InSb whiskers.
