Feasibility of testing the state of paramagnetic materials and products using magnetic resonance methods: III. Determination of characteristics of working matters of transducers of quantum magnetometers

Magnetometric characteristics of working matters having both the form of stable polycrystalline radicals and their mechanical mixtures with water and water solutions and the form of ultradisperse metallic lithium particles are determined. The conditions of existence of real values of these characteristics are established. In particular, it is shown that for the working matters the gyromagnetic ratio of the noncompensated electron and the resonance curve width must be attested under the conditions which ensure both the elimination of the influence of weak magnetic field effects and the g-tensor anisotropy (stable polycrystalline radicals) and the elimination of the influence of weak magnetic field effects and the skin effect (ultradisperse metallic lithium particles).
