Abstract
Using bicolor laser treatment by Nd:YAG 20ns laser (1064–532nm) and 180ns CO2 laser beams (10.6–5.3μm) it was shown a possibility of critical temperature enhancement in ferromagnetic superconducting MgB2/CrO2 bilayer films. The role of the phonon sub-system effectively interacting with 3d Cr originating localized trapping levels is discussed. The pump–probe laser kinetics for the probing second harmonic generation at 1064nm is explored in details to show principal role of the localized trapping levels. The relaxation of the processes after the switching off the photo inducing beams show the disappearance of the enhanced superconductivity after the 20–30s. The temperature dependence of the resistance show nonlinear dependence versus the pumping power and different optimal fundamental to writing power density beams ratio.
