Experimental study of emergent ground state behavior in Gd1-xCexNi5 (x = 0; 0.2; 0.5; 0.8 and 1) melt-spun ribbons

Abstract

The ground state physical properties of Gd1-xCexNi5 (x = 0; 0.2; 0.5; 0.8 and 1) melt-spun ribbons were investigated by X-ray diffraction, magnetization and specific heat measurements. The produced ribbon samples are single phases with the hexagonal CaCu5-type crystal structure. The magnetic transition temperature decreases with increasing Ce content. At a temperature around 100 K for the CeNi5 melt-spun ribbon, the spin fluctuations effect is visible.
