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≤Bappl≤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 μ+ energies at the various interstitial sites. This leads to the conclusion that at low temperatures μ+ in α-Fe occupy configurations related to octahedral interstitials with dipolar field Bdip=0.70 T.
