In this work we apply the time-dependent Ginzburg-Landau theory (TDGL) to calculate the magnetization M(H), the vortex configuration and the current density of mesoscopic samples in superconducting materials subjected to different linear temperature gradients. We solve the TDGL in a thin square film, immersed in a homogeneous external magnetic field H(t) applied perpendicular to its surface. We observe that the vortices enter at smaller magnetic fields when the sample temperature is higher. In turn, the vortexes always enter the surface
at a higher temperature.
