Incommensurate antiferromagnetic order in the manifoldly-frustrated SrTb${}_2$O${}_4$ with transition temperature up to 4.28 K

Abstract

The N$\acute{\mathrm{e}}$el temperature of the new frustrated family of Sr\emph{RE}${}_2$O${}_4$ (\emph{RE} = rare earth) compounds is yet limited to $\sim$ 0.9 K, which more or less hampers a complete understanding of the relevant magnetic frustrations and spin interactions. Here we report on a new frustrated member to the family, SrTb${}_2$O${}_4$ with a record $T_{\mathrm{N}}$ = 4.28(2) K, and an experimental study of the magnetic interacting and frustrating mechanisms by polarized and unpolarized neutron scattering. The compound SrTb${}_2$O${}_4$ displays an incommensurate antiferromagnetic (AFM) order with a transverse wave vector \textbf{Q}${}_{\mathrm{AFM}}^{0.5K}$ = (0.5924(1), 0.0059(1), 0) albeit with partially-ordered moments, 1.92(6) ${\mu }_{\mathrm{B}}$ at 0.5 K, stemming from only one of the two inequivalent Tb sites mainly by virtue of their different octahedral distortions. The localized moments are confined to the \emph{bc} plane, 11.9(66)${}^{\circ }$ away from the \emph{b} axis probably by single-ion anisotropy. We reveal that this AFM order is dominated mainly by dipole-dipole interactions and disclose that the octahedral distortion, nearest-neighbour (NN) ferromagnetic (FM) arrangement, different next NN FM and AFM configurations, and in-plane anisotropic spin correlations are vital to the magnetic structure and associated multiple frustrations. The discovery of the thus far highest AFM transition temperature renders SrTb${}_2$O${}_4$ a new friendly frustrated platform in the family for exploring the nature of magnetic interactions and frustrations.
