It was established that the magnetic nanopowder La0.6Ag0.2Mn1.2O3 has a large magnetocaloric effect at ТС, the appearance of which in a weak magnetic field of Н = 500 Ое is observed in a narrow temperature range of 27 – 42 °С. It is shown that in an alternating magnetic field with an amplitude of Hmax = 500 Ое and a frequency of f = 500 kHz, the appearance and growth of the specific loss power in the La0.6Ag0.2Mn1.2O3 nanopowder in the relaxation region of the hysteresis near the ТС is related to the effect of Neel relaxation of magnetization. It was established that the synthesized magnetic nanopowder of non-stoichiometric composition La0.6Ag0.2Mn1.2O3 has functional properties that allow it to be used as a nanopowder with a local hyperthermia intelligent control system.
