CuB2O4 的磁基态在 T = 1.8 K 时不相称，并在 T（小星）处经历连续相变到非共线相称反铁磁态，填充约 10 K。接近 T（小星）时，观察到填充的高阶磁卫星。在两个磁相中都观察到长程和短程磁序共存。这表明 Dzyaloshinskii-Moriya 相互作用和各向异性的关联导致了磁孤子晶格的形成。
The magnetic ground state of CuB2O4 is incommensurate at T = 1.8 K and undergoes a continuous phase transition to a noncollinear commensurate antiferromagnetic state at T(small star), filled approximately 10 K. Close to T(small star), filled higher-order magnetic satellites are observed. Coexistence of long- and short-range magnetic order is observed in both magnetic phases. This suggests that the association of the Dzyaloshinskii-Moriya interaction and anisotropy leads to the formation of a magnetic soliton lattice.
