Query: Magnetic order near 270 K in mineral and synthetic Mn$_2$FeSbO$_6$
  ilmenite   The structural and magnetic properties of Mn$_2$FeSbO$_6$ single-crystalline
mineral and ceramic samples synthesized under thermobaric treatment have been
investigated, and compared to theoretical predictions based on first-principles
electronic structure calculations. This ilmenite system displays a sharp
magnetic transition just below the room temperature related to a ferrimagnetic
ordering of the Mn$^{2+}$ and Fe$^{3+}$ cations, which makes Mn$_2$FeSbO$_6$ a
promising candidate for designing functional magnetic materials.
