Magnetic-ordered and superconducting units inside surface layers of PbTe:Eu crystals grown from melt by using the Bridgman method

Magnetic-ordered and superconducting units inside surface layers of PbTe:Eu crystals grown from melt by using the Bridgman method

Presented in this work are the results of the first systematic study of magnetic properties inherent to surface layers of PbTe:Eu crystals grown from melt with a low initial concentration of Eu impurity using the Bridgman method. The magnetic field dependences of magnetization at the temperat...
