Abstract |
The influence of 200 keV Ar-ion irradiation on the interlayer coupling in Fe/Cr multilayers exhibiting the giant magnetoresistance effect (GMR) is studied by the conversion electron Mössbauer spectroscopy (CEMS), magnetic hysteresis loops, magnetoresistivity and electric resistivity measurements and supplemented by the small angle X-ray diffraction (SAXRD).
