Abstract
Magnetization and Shubnikov-state in a mesoscopic superconducting sample (disk and square) with a Honeycomb-Kagome structure in regions with suppressed superconductivity, produced in the sample increasing the local temperature Td by using a continuous wave laser that emits a beam with a controlled heat output, are studied. The simple time-dependent Ginzburg-Landau model is used to describe the interaction of light with the superconducting sample, where the defects are include through the spatially-dependent-temperature. The quantized magnetic flux (vortices or Shubnikov-state) are located first in the depressed-superconducting regions (defects), in which is considered that Tcâ¯>â¯Tdâ¯>â¯T (Tc is the critical temperature of the sample and T the temperature of the thermal bath in which the sample is immersed). Different signatures on the magnetization and the Shubnikov-state are observed in the presence of defects with different sizes rd and Td. Thus it is possible to control the magnetic response of the sample and to manipulate the vortex configuration without any structural changes that could include another kind of material.
