We report a kinetic small angle neutron scattering study of the skyrmionlattice (SL) in MnSi. Induced by an oscillatory tilting of the magnetic fielddirection, the elasticity and relaxation of the SL along the magnetic fielddirection have been measured with microsecond resolution. For the excitationfrequency of 325 Hz the SL begins to track the tilting motion of the appliedmagnetic field under tilting angles exceeding $\alpha_c$ > 0.4{\deg}.Empirically the associated angular velocity of the tilting connectsquantitatively with the critical charge carrier velocity of approx. 0.1mm/sunder current driven spin transfer torques, for which the SL unpins. Inaddition, a pronounced temperature dependence of the skyrmion motion isattributed to the variation of the skyrmion stiffness. Taken together our studyhighlights the power of kinetic small angle neutron scattering as a newexperimental tool to explore, in a rather general manner, the elasticity andimpurity pinning of magnetic textures across a wide parameter space withoutparasitic signal interferences due to ohmic heating or Oersted magnetic fields.
