Abstract
For the first time high energy Helium-Silver laser which belongs to the category of metal-vapor lasers applied as microstructure promoter for optimally Ir-doped-MgB(2)sample.
The Ir-optimally doped Mg0.94Ir0.06B2 superconducting sample was selected from previously published article for one of authors themselves. The samples were irradiated by a three different doses 1, 2 and 3 h from an ultrahigh energy He Ag Laser with average power of 103 W/cm(2) at distance of 3 cm. Superconducting measurements and micro-structural features were investigated as function of He-Ag Laser irradiation doses. Results indicated that irradiations via an ultrahigh energy He-Ag-Laser promoted grains to lower sizes and consequently measured J(c)'s values enhanced and increased. Furthermore Tc-offsets for all irradiated samples are better than non irradiated Mg0.94Ir0.06B2.
