Abstract
We report on the magnetic structures of PrMn7O12, resolving both a high-temperature structure in common with the other R3+Mn7O12 systems and an additional low-temperature phase characterized by a superposed incommensurate (ICM) spin canting. A phenomenological model is developed to account for large magnetoelastic coupling immediately below the Curie temperature, demonstrating that A′B exchange is primarily responsible for the ferrimagnetic structures observed across the R3+Mn7O12 family. Finally, an analytical mean-field minimal model is presented that successfully accounts for all magnetic structures observed in this family of materials, including the canted commensurate and ICM ground states.
