- Title
Discrepancy in the low-temperature heat capacity of MgFeO and related problems.
- Authors

- Abstract
Evident discrepancy (by six times) between low-temperature heat capacities of two different samples of magnesioferrite (MgFeO) with a different thermal history is analogous to that (by four times) for franklinite (ZnFeO) found 50 years ago. The reason is supposed to be in the different magnetic ordering caused by different cation ordering after quenching-annealing. Magnetic nature of the discrepancy in low-temperature thermodynamic functions of minerals with variable cation ordering is out of quantitative consideration so far. This effect can also be found in all oxide phases of magnetic cations with the inversion parameter.
