Research of dependence of the curie constant of superparamagnetic nanopartycles suspension on magnetic field induction

Dependence the Curie constant of magnetite nanoparticles suspension on magnetic field induction is experimentally investigated in the work. The Curie constant was defined by values of an induction and intensity of magnetic field in the suspension measured by a method of nuclear magnetic resonance. The received reduction of the Curie constant with growth of magnetic field induction is explained by disorder of nanoparticle size. In the assumption of uniform function of nanoparticles distribution on volumes satisfactory compliance of theoretical and experimental dependences of the Curie constant on magnetic induction is obtained.
