Paper Abstract

Neodymium-Iron-Boron (NdFeB) is a material with important magnetic properties, mostly used in permanent magnet fabrication. Thin layers of NdFeB are needed for miniaturization in electrical engineering, electronics, and for high-tech devices. We applied pulsed lased deposition (PLD) and radio frequency plasma assisted pulsed lased deposition (RFPLD) in vacuum for obtaining thin films and nanostructures of NdFeB from stoichiometric targets, at different temperatures. The influence of the laser parameters (wavelengths and fluence), radio-frequency discharge power and substrate temperature on the NdFeB structures, composition and magnetic properties has been investigated. The obtained structures have been characterized by Auger electron spectroscopy (AES), Atomic Force Microscopy (AFM) and optical microscopy. Vibrating Sample Magnetometer (VSM) studies have been performed for specific magnetic characterization.
