Abstract:
The study of the functional parameters, technology and characteristics of powder ferrite materials to create a biocompatible environment. Using experimental studies of temperature dependences of magnetization in small fields $(H \ll H_à)$ in the high-temperature region, a dimensional effect associated with a change in the magnetic state of particles with volumes close to the critical was found. From the perspective of the use of particles of this ferrite as magnetic nanoagents in medical technologies, it is of interest to further clarify the optimal conditions for the formation of the SPM state of the particles directly in the therapeutic temperature range.
