Abstract
R3AlCx (R = Ce, Pr and Nd; x = 0-1) series has been synthesized by arc melting. Rietveld analysis of x-ray powder diffraction reveals cubic (Pm-3m) structure. A Kondo temperature TK ~ 1Â K is estimated for Ce3AlC0.65 from the susceptibility and resistivity data. Magnetic susceptibility measurements indicate antiferromagnetic (AFM) order for R = Pr (x = 0.8 and 1) and Nd (x = 0.6, 0.8 and 1) and ferromagnetic (FM) for Nd3Al. Metamagnetic behaviour in the magnetization curve indicates complex magnetic structure. Band structure calculations indicate growth of a pseudo-gap in the density of states (DOS) from Ce3AlC to Pr3AlC to Nd3AlC. The DOS calculations predict a metallic behaviour which is consistent with the resistivity measurements.
