On the Possibility of Determining the Curie Constant and Magnetic Susceptibility of Colloidal Solutions by Method of Nuclear Magnetic Resonance

A new universal technique was suggested to determine the Curie constant C and magnetic susceptibility of colloidal solutions placed in hermetically sealed vessels (for instance, ferrofluid cells) with an error of no more than 1.0%. Experimental research demonstrated that in the temperature range T from 283 to 323 K, in which ferrofluid cells are used, the Curie law is fulfilled. It was established that increase in temperature T of the colloidal solution from 324 to 363 K in a ferrofluid cell leads to an insignificant increase in C, which needs to be taken into account when conducting experiments using these cells. Results of research on colloidal solutions are presented in the paper.
