75.50.Ee - Opis:
- The magnetic structures of the polycrystalline samples of RAgSb$\text{}_{2}$ (R=Ce, Pr, Nd, Tb-Tm) are determined. All compounds crystallize in the tetragonal ZrCuSi$\text{}_{2}$-type of crystal structure and except CeAgSb$\text{}_{2}$ they are antiferromagnets with a Néel temperature of 11 K for R = Tb and 2 K for Tm. CeAgSb$\text{}_{2}$ below T$\text{}_{C}$=9.5 K is ferromagnet with the magnetic moment equal to 0.33μ$\text{}_{B}$ and parallel to c-axis. In NdAgSb$\text{}_{2}$ the sine modulated magnetic ordering described by the wave vector k = (0.5435,0,0) is observed. Below T$\text{}_{N}$ 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 TmAgSb$\text{}_{2}$ the coexistence of the two phases is observed at T = 1.4 K. With an increase in temperature only the incommensurate phase stays.zapisz i
