Аннотация
A technique for studying the magnetic susceptibility of colloidal solutions in a hermetically sealed glass volume (a ferrofluidic cell) is proposed. Experimental investigations have shown that Curie’s law holds in the temperature range of 283–323 K at which ferrofluidic cells are used. A further increase in the temperature of a colloidal solution in a ferrofluidic cell leads to an increase in the Curie constant C, which is due to the fact that the thermal motion of molecules destroys conglomerates with antiparallel magnetic moments of nanoparticles that have a binding energy of the order of kТ.
