We investigated effects of magnetic field H on antiferromagnetic (AF) structures in CeRh 1− x Co x In 5 by performing the elastic neutron scattering measurements. By applying H along the [1 0] direction, the incommensurate AF state with the propagation vector of q h 1 = (1/2, 1/2,0.297) observed at H = 0 is replaced by the commensurate AF state with the q c 2 = (1/2, 1/2,1/4) modulation above 2 T for x = 0.23, while the AF states with the q c 1 = (1/2,1/2, 1/2) and q h 2 = (1/2,1/2,0.42) modulations seen at H = 0 change into a single q c 1 -AF state above ~ 1.6 T for x = 0.7. These results suggest the different types of AF correlation for Co concentrations of 0.23 and 0.7 in an applied magnetic field H .
