    Any of a class of chemical compounds with the general formula RFeO, where R is any rare earth element.


  1. Orthoferrite

    An orthoferrite is any of a class of chemical compounds with the formula RFeO3. Orthoferrites have an orthorhombic crystal structure with a space group Pbnm and most are weakly ferromagnetic. At the Néel temperature TN the subsystem of iron ions orders into a slightly canted antiferromagnetic structure with antiferromagnetic moment G and a weak ferromagnetic moment F. The rare-earth ion subsystem acquires magnetization m due to an interaction with the iron subsystem. The orthoferrites are particularly interesting because of the presence of an antisymmetric exchange interaction which involves the vector cross product of neighboring spins as opposed to the usual scalar product. In the absence of this interaction, the orthoferrites would be antiferromagnetic. Its presence leads to a small canting of the sublattices, making the orthoferrites “weak” ferromagnets with 4πMs = 100 G. Another interesting feature of these materials is the fact that some of them exhibit a transition as a function of temperature, in which the direction of the antiferromagnetically ordered spins and consequently also of the net magnetization rotates by 90°.
