Ising Spin Ladders of Orthopyroxene CoGeO&sub(3) / P.A.Maksimov, [a.o.]. – Text : electronic // Physical Review B. – 2025. – Vol. 112, No. 22. – P. L220407. – URL: https://doi.org/10.1103/fxrl-yr9g.
We present thermodynamic and spectroscopic measurements for an orthopyroxene CoGeO&sub(3) with magnetic Co&sup(2+) ions that form quasi-one-dimensional ladders. We show that noncollinear magnetic order below 𝑇𝑁=32 K can be stabilized by a strong local easy-axis anisotropy of 𝑗eff=1/2 moments, which is induced by ligand octahedra distortions. Extraction of a magnetic Hamiltonian from inelastic neutron scattering measurements supports this interpretation and allows us to establish an effective magnetic model. The resulting exchange Hamiltonian justifies CoGeO3 as a realization of an Ising spin ladder compound.
