Abstract

Gadolinium stearate is synthesized in the form of a micropowder. Its composition is determined by elemental and energy dispersive X-ray analyses: [Gd(C17H35COO)3]·(H2O)2.42. The splitting parameters in the zero field (D and E) are determined for the EPR spectrum of the gadolinium stearate powder synthesized at 77 K. The magnetic susceptibility is calculated from the integral intensities of the EPR spectra of the gadolinium stearate powder recorded in a range of 77–293 K. The Curie temperature (θ = 0.16 K) and Weiss constant (С = 7.53 cm3 K mol–1) are determined. The effective magnetic moment is calculated (μeff = 7.8 ± 0.14 μВ), which is constant in the whole temperature range studied for the synthesized gadolinium stearate powder.
