Resumen:
Using the first-principles real-space linear muffin-tin orbital method within the atomic sphereapproximation (RS-LMTO-ASA) we study hyperfine and local magnetic properties ofsubstituted pure Fe and FeCu clusters in an fcc Cu matrix. Spin and orbital contributions tomagnetic moments, hyperfine fields and the M¨ossbauer isomer shifts at the Fe sites in Feprecipitates and FeCu alloy clusters of sizes up to 60 Fe atoms embedded in the Cu matrix arecalculated and the influence of the local environment on these properties is discussed.
