Abstract
In the work presented the magnetic properties of the high pressure ilmenite phase Mn_2FeSbO_6 are investigated in detail. It is shown that Mn_2FeSbO_6 ilmenite is ferrimagnetic (T_N approximate to 270 K) and exhibits a near-zero coercive field H_C. Furthermore, the Mn^2+-Mn^2+, Fe^3+-Fe^3+ and Mn^2+-Fe^3+ magnetic exchange interactions exhibit gradual and continuous variations with temperature and magnetic field. The ferrimagnetic moment is unsaturated even at 120 kOe below the theoretical value of 5 mu_B per f.u.
