      abstract     = {We combine single-crystal neutron diffraction studies and
                      Monte Carlo simulations to determine the spin structures and
                      finite-temperature phase diagram of the spin-5/2
                      triangular-lattice antiferromagnet Na2⁢BaMn⁢(PO4)2 in
                      magnetic field. With the application of a magnetic field in
                      two different directions, namely along the 𝑐 axis and in
                      the 𝑎⁢𝑏 plane of the trigonal symmetry, we track the
                      evolution of the spin structure through changes of the
                      magnetic propagation vector. We account for these results
                      with a minimal Heisenberg Hamiltonian that includes
                      easy-axis anisotropy and weak, frustrated interlayer
                      couplings in addition to intralayer exchange. Guided by
                      representation analysis, we refine symmetry-allowed modes to
                      the measured intensities and obtain the spin structures for
                      all field-induced phases, which we compare quantitatively
                      with simulated configurations. Taken together, our
                      measurements and simulations show that frustrated interlayer
                      exchange—rather than purely two-dimensional
                      physics—organizes the unexpectedly rich field-induced
                      phases of Na2⁢BaMn⁢(PO4)2.},
