      abstract     = {The Néel temperature of the new frustrated family of
                      SrRE2O4 (RE = rare earth) compounds is yet limited to ~0.9
                      K, which more or less hampers a complete understanding of
                      the relevant magnetic frustrations and spin interactions and
                      an exploration of potential interesting properties. Here we
                      report on a new frustrated member to the family, SrTb2O4
                      with a record TN = 4.28(2) K, and an experimental study of
                      the magnetic interacting and frustrating mechanisms by
                      polarized and unpolarized neutron scattering. The compound
                      SrTb2O4 displays an incommensurate antiferromagnetic (AFM)
                      order with a transverse wave vector Q0.5 KAFM = (0.5924(1),
                      0.0059(1), 0) albeit with partially-ordered moments, 1.92(6)
                      μB 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 bc
                      plane, 11.9(66)° away from the 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 SrTb2O4 a new friendly
                      frustrated platform in the family for studying the nature of
                      magnetic interactions and frustrations and exploring
                      potential macroscopic functionalities and new quantum
                      states.},
