Abstract
The magnetic insulator Nd$_3$BWO$_9$ has been proposed as a proximate
spin-liquid candidate, realizing the highly frustrated breathing kagome
lattice. We report a combination of single-crystal neutron scattering studies
and numerical simulations, showing that it is the inter-plane couplings that
determine the physics. To explain the exotic magnetism, we derive a simple
one-dimensional Ising model composed of twisted triangular spin-tubes, i.e.,
triple braids of Ising spin chains with almost-orthogonal anisotropy frames and
competing ferro-antiferromagnetic interactions. This model can account for the
ground state, excitations, the numerous field-induced fractional magnetization
plateau phases and incommensurate magnetic correlations at elevated
temperatures.
