It was noted that the electron drag force on a moving dislocation in a magnetic field, H, introduced a sharp maximum in the drag stress (tilt-effect) when H was parallel to the dislocation line. The width of this maximum was proportional to the radius of the effective electron-dislocation interaction which, in the linear theory, was of the order of the Burgers vector, b. However, by using a non-linear approach, it was shown that this width was much larger than in the linear case and was given by the expression, (b/R)⅓; where R was the cyclotron radius. The estimate for the width of the tilt-effect, as obtained using the non-linear approach, was in good agreement with experimental results; unlike the width deduced from the linear theory.
