Difracción de rayos-X, análisis térmico diferencial y propiedades magnéticas del AgCrSe<inf>2</inf>

Abstract:

olycrystalline samples of AgCrSe2 were prepared by the melt and anneal technique. The composition of the samples was determined by measurements of energy dispersive spectrometry. Measurements of X-ray powder diffraction at room temperature were used to give lattice parameter values. Transition temperatures were obtained from differential thermal analysis (DTA) measurements. Low-field measurements of magnetic susceptibility Chi; were made as a function of temperature in the range 5 to 300 K. The value of T N, the critical temperature, was obtained from the cusp in the Χ versus T curve. The Curie-Weiss temperature was determined from the 1/Χ versus T curve.
