A decrease in the electrical conductivity of polyacetylene films when an external magnetic field is switched on, saturating in fields 100 Oe, is observed. The effect is explained by the dependence of the hopping probability of current carriers along soliton levels on the spin state of polaron-soliton paramagnetic particle pairs.
