Magnetic properties of the RNiIn4 (R = Ce, Pr, Nd) series of intermetallic compounds grown by the metallic flux method

This work focuses on the synthesis, structural and magnetic characterization, and the effects of the Crystal Electric Field (CEF) of RNiIn4 (R = Ce, Pr, Nd) compounds. By using the metal flux technique, high-quality single crystals were obtained and analyzed X-ray diffraction and confirmed the formation of a single phase for all compounds and revealed their crystallization in a orthorhombic structure. Magnetic susceptibility measurements revealed antiferromagnetic in order ing temperatures (TN) at 4.02 K, 2.37 K and 4.06 for Ce, Pr, and Nd, respectively. Specific heat data corroborated these findings. The results indicate the easy axis of magnetization lies in the ab-plane for Ce and Nd, and along the c-axis for Pr. •The research highlighted the process of synthesizing single crystals using the metal flux method.•The research explores the use of rare earth elements in the RNiIn4 compound family.•The research highlights the results obtained from the structural, magnetic, and specific heat characterization of the RNiIn4 sample family.
