Structural, magnetic and Mössbauer studies of Fe–Cu granular films

X-ray diffraction, magnetization and Mossbauer effect investigations have been performed for the sputtered Fe sub 0.2 Cu sub 0.8 thin films. A segregation forming isolated body-centred cubic Fe grains in the face-centred cubic Cu matrix with an average diameter between 1 and 40 nm took place upon an...

Description
Summary:X-ray diffraction, magnetization and Mossbauer effect investigations have been performed for the sputtered Fe sub 0.2 Cu sub 0.8 thin films. A segregation forming isolated body-centred cubic Fe grains in the face-centred cubic Cu matrix with an average diameter between 1 and 40 nm took place upon annealing in the temperature range from 100 to 500 deg C. In addition, the magnetic coercive field is found to be enhanced and reaches a value of 37 mT for the sample annealed at 400 deg C. A perpendicular surface anisotropy constant K sub S = 0.04 mJ m exp -2 is deduced. Surface spin configurations are discussed for the granular films investigated.
