Structural and magnetic investigations on Mn-implanted beta-Iron-Disilicide — •Frank Stromberg1, Helfried Reuther2, and Werner Keune11Angewandte Physik, Universität Duisburg-Essen, 47048 Duisburg, Germany — 2Forschungszentrum Rossendorf, 01314 Dresden, Germany

100 nm thick epitaxial beta-Iron-Disilicide films were grown on Si(100) substrates by MBE and ex-situ implanted with Mn-ions at energies of 90 and 150keV.

The doses varied from 1E16 to 1E17. X-Ray and Mössbauer spectroscopy confirmed the amorphization of the implanted films.

Hall measurements exhibit n-type behavior of the implanted samples whereas literature states that they should be p-type conducting.

The conductivity of the implanted samples is strongly enhanced but for the sample with the highest dose it drops.

Anomalous Hall effect and Magnetoresistance measurements were performed but a conclusive hint pointing at magnetic effects is only possible after SQUID measurements which are currently performed.
