Abstract

Samples with nominal compositions HoBa2Cu3O y and (Ho0.97Sn0.03)Ba2Cu3O y are obtained by the melt-texture-growth (MTG) method and their superconducting properties are investigated. It is shown that the Sn-doping increases the irreversibility field and the upper critical field of the pristine compound. Both the undoped and Sn-doped samples undergo a vortex glass-vortex liquid transition. The observed phenomena are discussed.
