Determination of the magnetic domain size in the ferromagnetic   superconductor UGe2 by three dimensional neutron depolarization
  Three dimensional neutron depolarization measurements have been carried out on single-crystalline UGe2 between 4 K and 80 K in order to determine the average ferromagnetic domain size d. It is found that below T_C = 52K uniaxial ferromagnetic domains are formed with an estimated magnetic domain size of d = 4 - 5 micrometer.
