Mesoscale vortex pinning landscapes in a two component superconductor

•Magnetization and vorticity depends on the size and temperature of the defect•Magnetic susceptibilty is sensible to slow changes of temperature of the defect.•The vortex structure depends on the number and size of the defect We considered several mesoscale pinning/anti-pinning landscapes simulated with the parameter α(T) in the Ginzburg Landau free-energy density in a mesoscopic superconducting square of size L2. We analyzed the effects of the size, local critical temperature, position and number of the pinning/anti-pinning centers on the vortex configurations and magnetic response for several values of the Ginzburg-Landau parameter κ ([1 ≤ κ ≤ 8]). We shown that the fields depends strongly on the local critical temperature, configuration and number of the defects on the sample.
