Synthesis of FeCo thin films by advanced PLD — •Christian Lange, André Holz, Hendrik Schikora, and Peter Schaaf — Universität Göttingen, II. Physikalisches Institut, 37077 Göttingen, Germany

FeCo alloys of near-equiatomic composition offer exceptional magnetic properties. In this work, FeCo thin films were synthesized using advanced pulsed laser deposition, i.e. ion beam assisted deposition and different bias voltages were applied to study the influences on microstructure and magnetic properties of the films.

Structure analyses were performed with Rutherford backscattering spectrometry (RBS), X-Ray Diffraction (XRD) and conversion electrons Mössbauer spectroscopy (CEMS), while magnetic properties were examined by magneto-optical Kerr effect (MOKE) and magnetic orientation Mössbauer spectroscopy (MOMS).

Results show a strong correlation between deposition parameters (gas atmosphere and pressure, deposition rate) and the magnetic properties of the synthesized thin films.
