Magnetic Hyperfine Structure

ABSTRACTThe radio-frequency collapse of the magnetic hyperfine structure in the Mössbauer spectra is employed to study directly the short range order in amorphous Fe-M-B-Cu (M: Zr, Ti, Ta, Nb, Mo) alloys via the electric quadrupole hyperfine interaction. The shape of the quadrupole splitting distributions obtained from the rf collapsed spectra strongly suggests the existence of two short range orders with a high and low local content of iron. The decrease of boron content in FeZrB alloys leads to a more symmetric local structure experienced by Fe atoms.

Kinetics Of

The kinetics of short-range order (SRO) formation was investigated in the alloy Au25Ag25Pd50by using the residual electrical resistometry. The resistivity was found to increase with the formation of SRO. The resistivity values varied linearly with respect to the inverse of temperature, characterizing the different states of SRO. The analysis of isothermal experiments obeying the fundamental laws showed that the SRO kinetics followed the two-exponentials law. The characteristic time constants for the SRO formation corresponding to various annealing temperatures in the isothermal annealing process and the activation enthalpies were determined with high accuracy. The time constants for the SRO formation and destruction were different, implying that the reaction paths in these processes are different. Further, the crossover experiments confirmed the existence of two-exponential kinetics and the variation of the time constants.
