Hj. Blythe et H. Kronmuller, MAGNETIC-RELAXATION IN PD3FE FOLLOWING LOW-TEMPERATURE ELECTRON-IRRADIATION, Physica status solidi. a, Applied research, 138(1), 1993, pp. 281-296
Magnetic relaxation measurements are made in the temperature range 4 t
o 460 K on both ordered and disordered Pd3Fe following irradiation wit
h 3 MeV electrons. The temperature of irradiation is 40 K and the dose
ranges from 10(22) to 10(23) e- m-2. Well-defined relaxation processe
s are observed at 34; and 74 K in the ordered samples, which are attri
buted to the reorientation of intrinsic interstitial-type defects. On
anneal to higher temperatures, a relaxation evolves at 230 K, again in
the ordered samples; this is interpreted as a divacancy reorientation
.
