Phase states and magnetic structure of superconducting inclusions in narrow-gap semiconductor matrices
SQUID magnetic measurements have been performed on a series of PbTe narrow-gap semiconductors with n- and p-type conductivity in the field of temperatures 1.7-20 K and magnetic fields up to 1 Oe. Is shown that in a matrix PbTe are available microscopic inclusions of lead with the minimum sizes 1300 angstrom with concentration of atoms of lead in them N approximately (1 divided by 5) X 1018 cm-3 and phase transition characteristic for II type superconductor.
