Magnetic interactions of Chains formed by ferromagnetic spheres

摘要

General properties of sphere-chain and chain-chain structures are analysed for homogeneously magnetized spheres. For field aligned structures the local maximum of the magnetic force is observed at H_0/M_S ≈ 0.5. The magnetic saturation effects are accounted by the Frolich-Kennelly law. Outlines of the approximate methodology of multi-chain interaction are given together with the test results.
