✦ Synopsis

Neutron depolarization studies were performed on single crystals of the superconducting materials in order to elucidate the mixed state below the critical temperature by changing the cooling magnetic field. The quatitati~ analysis of the wavelength dependence of the depolarization shows that the magnetic flux forms the vortex line in the bulk crystal. The lower critical field is readily determined and also the penetration depth of the magnetic flux was determined under the simple assumption.
