Аннотация: The needle shape single crystals Co3-x MnxO2BO3 with ludwigite structure have been prepared. According to the X-ray diffraction data the preferable character of distinct crystallographic positions occupation by Mn ions is established. Magnetization field and temperature dependencies are measured. Paramagnetic Curie temperature valuПоказать полностьюe Theta = -100 K points out the predominance of antiferromagnetic interactions. Spin-glass magnetic ordering takes the onset at T-N=41 K. The crystallographic and magnetic properties of Co3O2BO3:Mn are compared with the same for the isostructural analogs Co3O2BO3 and CoO2BO3:Fe.
