On the Possibility of Studying Ferrofluids by a Nuclear Magnetic Magnetometer with a Flowing Sample

In this paper, we consider a new method that employs a highly sensitive nuclear magnetic magnetometer with flowing water to determine the magnetic susceptibility and Curie constant of magnetic fluids with an error no greater than 1.0%. The Curie law was shown to be fulfilled in the temperature range of 283–323 K, in which ferrofluidic cells are used. A further increase in the temperature of the ferromagnetic fluid leads to an insignificant change in the Curie constant. The results of experimental studies are presented.
