| Abstract: | Long term stability of the coercivity and57Fe Mössbauer parameters (magnitude and average orientation of hyperfine induction) at ca 150 °C was tested at three TM-M type amorphous alloys (Fe83B17, Fe40Ni40B20 and Co66Fe5Cr7Si8B14) up to 5000 hrs. Correlations between the Mössbauer and magnetic quantities were found and their possible causes are discussed. |
