We combine neutron diffraction with low temperature magnetization to investigate the magnetic periodicity in the vicinity of these plateaus. We find these steps to be characterized by metastable and spatially short-range (ξ∼10 Å) magnetic correlations with antiphase boundaries defining a local periodicity of ⟨ˆT2⟩=↑⏐⏐⏐⏐↓ to ⟨ˆT3⟩=↑⏐⏐↑⏐⏐⏐⏐↓ and ⟨ˆT4⟩=↑⏐⏐↑⏐⏐⏐⏐↓⏐⏐↓ or ↑↑↑↓ spin arrangements. This shows the presence of spatially short range and metastable/hysteretic, commensurate magnetism in Ising magnetization steps.Show less >
