Abstract: Abstract: μ <superscript>+</superscript> SR measurements have been performed on Cr single crystals at temperatures 60 mK≤T≤295 K in applied magnetic fields 0≤B <subscript>appl</subscript>≤1.5 T. The temperature dependence of the observed precession frequencies and transverse relaxation rates can be explained by the assumption that theμ <superscript>+</superscript> are hopping between adjacent tetrahedral interstices. At temperaturesT≤11 K evidence for an interaction between theμ <superscript>+</superscript> and the spin-density waves in Cr has been found. The directions and magnitudes of the lattice magnetic moments are unaffected by the applied magnetic fields.
