摘要：

Spin and orbital magnetic moments in hole doped manganite La0.7Ca0.3Mn1-xAlxO3 (x = 0, 0.02, and 0.06) have been scrutinized using experimental spin momentum densities. An analysis of magnetic Compton profiles shows that the spin moment of Mn 3d has a major contribution towards the total spin moment and its contribution decreases as we increase the concentration of Al. The present experiment along with magnetization data predict orbital moment of -0.29 +/- 0.03 mu(B)/f.u. in the parent compound (x = 0), which almost disappears on substitution of Al. The results are explained on the basis of imbalance in Mn3+ and Mn4+ charge ratio in these compounds. (C) 2011 American Institute of Physics. [doi:10.1063/1.3624843]
