In this work,a solid solution of chromite-manganite of the composition Y0,5Ca0,5Cr0,5Mn0,5O3 was synthesized using the sol-gel method. Based on the results of experimental studies of the magnetostatic properties of the polycrystalline system Y0,5Ca0,5Cr0,5Mn0,5O3. It is found that the predominant is the intracrystalline ferromagnetic interaction, while the intercrystalline interaction is antiferromagnetic in nature.In the field of 2000 Oe and 5000 Oe at a temperature of 5 K, the magnetic moment is not even positive. These dependencies were obtained after the sample was in a large negative field. This initial moment is approximately equal to the residual moment on the hysteresis loop for a temperature of 5 K. When the external field is increased gradually, for example, in increments of 250 Oe, this moment increases to 1.2 emu/g at 2000 Oe. Based on the results of magnetostatic measurements, it was found that hysteresis loops of magnetization are observed at low temperatures.
