Abstract
The magnetic structures of the polycrystalline samples of RAgSb2 (R = Ce, Pr, Nd, Tb-Tm) are determined. All compounds crystallize in the tetragonal ZrCuSi2-type of crystal structure and except CeAgSb2 they are antiferromagnets with a Néel temperature of 11 K for R = Tb and 2 K for Tm. CeAgSb2 below TC = 9.5 K is ferromagnet with the magnetic moment equal to 0.33μB and parallel to c-axis. In NdAgSb2 the sine modulated magnetic ordering described by the wave vector k = (0.5435,0,0) is observed. Below TN a collinear antiferromagnetic structure with the magnetic (a, a, 2c) for R = Pr and (2a, a, c) for R = Tb, Dy, Ho, and Er is observed. For Ho-compound with an increase in temperature the coexistence of two structures is observed: commensurate collinear and incommensurate sine modulated. In TmAgSb2 the coexistence of the two phases is observed at T = 1.4 K. With an increase in temperature only the incommensurate phase stays.
