Magnetic Structure and the Spin-Crossover Mechanism in Ludwigite Со 3BO 5

Zamkova, N.G., Zhandun, V.S., Ovchinnikov, S.G.// JETP Letters//

A spin-crossover mechanism in ludwigite Со3BO5 is proposed on the basis of the DFT calculation with SCAN potentials. The role of separate exchange interactions in the establishment of the long-range magnetic order is demonstrated within the Monte Carlo method.
