The Dependence of Magnetic Moments on Magnetic Impurities of Ni in Eu_1.86Ce_0.14Cu_1-yNi_yO_4+a-d

Abstract:

The partially substitution of magnetic impurity Ni for Cu in electron-doped superconducting cuprates of Eu_2-xCe_xCu_1-yNi_yO_4+a-d with x = 0.14 and y = 0, 0.01 and 0.02 has been studied in order to investigate the effect of Ni impurity on structure and the value of magnetic moments per unit volume extracted from susceptibility data in under-doped region. Magnetic-susceptibility measurements were carried out at low temperatures down to 2 K. For sample with y = 0, diamagnetic behavior is observed starting from about 9 K. The superconductivity disappeared at y ³ 0.01. The values of magnetic moment in every volume unit decreased with increasing Ni.
