80 K superconducting Bi-Sr-Ca-Cu-O layers prepared by laser ablation in the air

The method of laser ablation in air, i.e. without the use of a vacuum chamber, was employed to prepare highly oriented Bi-Sr-Ca-Cu-O layers with a critical zero-resistance temperature of K. The properties of these layers were studied by the SEM and x-ray diffraction methods and by measuring the magnetic susceptibility.
