      abstract     = {The magnetic structure of the “nonmetallic metal”
                      FeCrAs, a compound with the characters of both metals and
                      insulators, was examined as a function of temperature using
                      single-crystal neutron diffraction. The magnetic propagation
                      vector was found to be k=(1/3,1/3,0), and the magnetic
                      reflections disappeared above TN=116(1)K. In the ground
                      state, the Cr sublattice shows an in-plane spiral
                      antiferromagnetic order. The moment sizes of the Cr ions
                      were found to be small due to strong magnetic frustration in
                      the distorted kagome lattice or the itinerant nature of the
                      Cr magnetism and vary between 0.8 and 1.4μB on different
                      sites as expected for a spin-density-wave- (SDW-) type
                      order. The upper limit of the moment on the Fe sublattice is
                      estimated to be less than 0.1μB. With increasing
                      temperature up to 95 K, the Cr moments cant out of the ab
                      plane gradually with the in-plane components being
                      suppressed and the out-of-plane components increasing in
                      contrast. This spin reorientation of Cr moments can explain
                      the dip in the c-direction magnetic susceptibility and the
                      kink in the magnetic order parameter at TO∼100K, a second
                      magnetic transition which was ignored before. We have also
                      discussed the similarity between FeCrAs and the model
                      itinerant magnet Cr, which exhibits spin-flip transitions
                      and SDW-type antiferromagnetism.},
