Figure 4.
Transverse muon-spin rotation data. (a) Fourier spectra measured in an applied field of B 0 = 150 mT for a 40-nm-thick film of FeGeL. Evolution with temperature of (b) the diamagnetic shift and (c) the relaxation rate λ for the two FeGe films at two values of the applied field B 0. Temperature-activated behaviour is evident above T = 260 K, as described in the text.
