Diamagnetic soliton at twin boundary
Burmistrov S. N. , Dubovskii L. B.
Near a twinning plane, the susceptibility blows up as χ ос В 2 as В => 0. It follows that there is an induced surface diamagnetism, independent of the temperature, with a domain size ~100 A and with a magnetic field ~10 -107 Oe in the domain.
