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