Anisotropy in magnetic behaviour of R (R = La, Ce, Pr, Nd, Sm, Dy and Gd)CrSb3

Cr in LaCrSb3 shows dual character with two coexisting magnetic interactions below 100 K along two different crystallographic directions. The anisotropy of crystal structure plays an important role here. With study of rest of the members of the series the aim was to understand the effect of adding f moment on this unusual magnetism of Cr, which in turn enriches our knowledge of d-f magnetic interplay. The magnetism in these systems was studied with susceptibility χ(T), isothermal magnetization M(H), resistivity ρ(T), specific heat Cp(T) and neutron diffraction measurement. (author)
