Abstract :
Pulsed Laser Deposition (PLD) using a femtosecond laser has improved the surface roughness, quality of thin films and deposition time significantly over nanosecond lasers. However characterizing these thin films especially the composition using Energy Dispersive X-ray Spectroscopy (EDS) is challenging. We report the successful growth and characterization of thin films of giant magnetocaloric Gd5Si1.3Ge2.7 using femtosecond PLD. We also report that annealing of Gd5Si1.3Ge2.7 thin film at 1000 K showed disappearance of particles on the film and the phase transition in the magnetic measurements.
