Phys. Rev. Lett. article on unusual magnetization jumps in mixed-spin oxide systems

This Phys. Rev. Lett. article describes the low-temperature freezing dynamics of the hemo-ilmenite mixed-spin oxide system. Above the Fe(III) percolation threshold unusual magnetic jumps occur at low temperatures (< 3 K), which is explained by a layerwise partitioning resulting from strong exchange and superexchange interactions that generate a collective rotation of the magnetic moments within this quasistochastic system.
