Full-Heusler Co-based alloys grown by pulsed laser ablation: structural, optical and magnetic characterizations

摘要

This paper concerns the study of growth and characterizations of Co2YZ with Y an element of transition metal group and Z, a III-V group element deposited onto Si, GaAs and InAs substrates. Two PLD configurations have been explored, the conventional 1-Beam-PLD and the 2-Crossed-Beams-PLD one. We demonstrated that depending on the configuration we got Co2YZ polycrystalline structure with unwanted droplets or droplet-free, single crystalline oriented thin films at substrate temperature as low as 353 K. Optical conductivity and magnetic properties are presented.
