Abstract
This work was supported by the projects VEGA 2/0032/16, VEGA 1/0956/17, VEGA 1/0611/18, VEGA 1/0053/19, APVV-16-0079 and the Spanish MINECO MAT2017-83631-C3-R
Highlights
The study of rare earth (RE) compounds has a long history because of their interesting physical properties due to 4f -localized magnetism, where competition between RKKY exchange interaction and Kondo effect is observed
The results confirmed that all prepared samples crystallize in the CaCu5 hexagonal crystal structure, so that the Vegard’s law can be applied
With the increase of the Ce content, the unit cell is expanding, which is consistent with the larger Ce volume with regard to Gd
Summary
The study of rare earth (RE) compounds has a long history because of their interesting physical properties due to 4f -localized magnetism, where competition between RKKY exchange interaction and Kondo effect is observed. One of these groups of compounds is RENi5, for which some aspects have already been investigated [1,2,3]. In this series of rare earth materials Ni atoms are nonmagnetic, but they are very close to the onset of magnetism [4]. The main aim of this paper is to experimentally study the spin fluctuation (SF) effect on Ce/Gd substitution, and analyse the disappearance of the magnetic transition in the studied system, using for it different experimental methods
