摘要：
The spin-precession frequencies and the transverse spin relaxation rates of positive muons (mu+) have been measured on two elastically strained alpha-Fe single crystal platelets as well as on an unstrained reference alpha-Fe crystal at temperatures down to 2.7 K in applied magnetic field 0 less-than-or-equal-to B(appl) less-than-or-equal-to 3 T. The drastic effects of the strains may be qualitatively understood in terms of their influence on both the magnetic domain structure and the mu+ energies at the various interstitial sites. This leads to the conclusion that at low temperatures mu+ in alpha-Fe occupy configurations related to octahedral interstitials with dipolar field B(dip) = 0.70 T.
