It is found that the magnetoplastic effect in C
60 single crystals in a pulsed magnetic field with induction larger than 10 T changes its sign in the vicinity of the phase
transition at
T
c
=250–260 K: crystal strengthening is observed for
T<
T
c
, and softening occurs for
T>
T
c
. This indicates a change in the crystal lattice structure in the magnetic field.
