Аннотация:NiCrBO has been synthesized and investigated by X-ray diffraction, dc magnetization, and specific heat measurements. The unusual cation distribution has been established: the M1 and M3 sites are occupied by Ni ions, the M2 site is by Cr3＋ ions, and the M4 site is mixed, featuring both Ni and Cr3＋ ions. The magnetic order onsets at T 140 K, which is confirmed by a -type peak in specific heat, followed by the dome-shaped anomaly of the magnetization at about 30 K. In the magnetically ordered state, a remarkable sequence of temperature-induced magnetization reversal sensitive to the measurement's regime is observed. Dominant antiferromagnetic interactions are characterized by the Weiss temperature −73 K. The effective magnetic moment of 5.37 per formula unit is close to the spin-only one. The effect of the cation distribution on the magnetic properties is discussed.
