Abstract:
The neutron star crust magnetodynamics is demonstrated to exhibit erratic jumps at the fields corresponding to a sharp change of nuclide magnetic moments induced by quantization effects. Such a noise originates from magnetic avalanches and shows intensity and statistical properties which are favorably compared to the burst activity of soft gamma repeaters.
