Abstrakt: Experimental data on the magnetic properties of magnetite-silica composite nanoparticles are presented. The anhysteretic remanent magnetization and curves for its destruction by an alternating magnetic field were obtained at room temperature. The experimental data are compared with the theoretical values for anhysteretic remanent magnetization calculated based on the model of interacting superparamagnetic particles. It is shown that the results agree in order of magnitude. [ABSTRACT FROM AUTHOR]
