      abstract     = {We report on the first single crystal study of SrTm2O4.
                      Magnetization measurements along the crystallographic axes
                      of a nearly stoichiometric Sr1.07(3)Tm2.07(6)O4.00(2) sample
                      show either a positive or a negative Curie–Weiss
                      temperature indicative of a competition between
                      antiferromagnetic and ferromagnetic couplings. The
                      field-dependent magnetization suggests an effective Zeeman
                      splitting of the high-level J-multiplets above ∼8.3 T and
                      that the paramagnetism may originate from only one of the
                      two inequivalent Tm3+ crystallographic sites. Our
                      single-crystal polarized neutron scattering and powder
                      unpolarized neutron diffraction data show no evidence for
                      either long- or short-range magnetic order even down to
                      ∼65 mK. We reveal two TmO6 octahedral distortion modes,
                      i.e., one distortion is stronger than the other especially
                      at low temperatures, which is attributed to different
                      crystal fields of the two inequivalent octahedra. Therefore,
                      the compound SrTm2O4 is unique and different from its
                      brethren in the family of frustrated SrRE2O4 (RE = rare
                      earth) magnets. We propose that crystal field anisotropy may
                      dominate over weak dipolar spin interactions in SrTm2O4,
                      thereby leading to a virtually non-ordered magnetic state.},
