Abstract:

High quality polycrystalline Er3AlCx (x = 0.8 and 1) system is synthesized using conventional tri arc melting. X-ray diffraction of Er3AlC is analyzed using Rietveld method which reveals single phase formation with Pm-3m cubic perovskite structure. Susceptibility curve indicates antiferromagnetic ordering at Neel temperatureTN=3.1 K. The values of θp and μeff deduced from inverse susceptibility curve are consistent with magnetic ordering temperature and theoretical value for Er3+ ion, respectively. Metamagnetic transition is found at 10 kOe.
