Magnetic properties of metallic glasses based on Fe−Cr from Mössbauer spectroscopy

Abstract Spectra of metallic foils Fe80−x Cr x B2 (x=6, 10, 15, 20) and Fe60Cr20B12Si8 were measured at range 4.2 K–300 K. Mössbauer data were analysed by Window’s Hesse-Rübartsch’s and Janot’s methods. The influence of the temperature and the Cr-content is discussed. The coefficientB 3/2 in Bloch’s...

Abstract Spectra of metallic foils Fe80−x Cr x B2 (x=6, 10, 15, 20) and Fe60Cr20B12Si8 were measured at range 4.2 K–300 K. Mössbauer data were analysed by Window’s Hesse-Rübartsch’s and Janot’s methods. The influence of the temperature and the Cr-content is discussed. The coefficientB 3/2 in Bloch’s law was calculated. Curie and crystallization temperature were taken from the DTA-DTMG method [1]. For finding the Curie temperature of the sample Fe60Cr20B20 we used ac susceptibility, but this sample is not homogeneous. Ausführliche Beschreibung
