      abstract     = {We show that frustrated quasidoublets without time-reversal
                      symmetry can host highly unconventional magnetic structures
                      with continuously distributed order parameters even in a
                      single-phase crystal. Our study comprises a comprehensive
                      thermodynamic and neutron diffraction investigation on the
                      single crystal of TmMgGaO4, which entails non-Kramers Tm3+
                      ions arranged on a geometrically perfect triangular lattice.
                      The crystal electric field randomness caused by the
                      site-mixing disorder of the nonmagnetic Mg2+ and Ga3+ ions
                      merges two lowest-lying crystal electric field singlets of
                      Tm3+ into a ground-state quasidoublet. Well below
                      Tc∼0.7  K, a small fraction of the
                      antiferromagnetically coupled Tm3+ Ising quasidoublets with
                      small inner gaps condense into two-dimensional up-up-down
                      magnetic structures with continuously distributed order
                      parameters, and give rise to the columnar magnetic neutron
                      reflections below μ0Hc∼2.6  T, with highly
                      anisotropic correlation lengths, ξab≥250a in the
                      triangular plane and ξc<c/12 between the planes. The
                      remaining fraction of the Tm3+ ions remain nonmagnetic at 0
                      T and become uniformly polarized by the applied longitudinal
                      field at low temperatures. We argue that the similar model
                      can be generally applied to other compounds of non-Kramers
                      rare-earth ions with correlated ground-state quasidoublets.},
