摘要：
We present analytical sum-rules for the electron energy loss chiral magnetic dichroism experiment. Predictions of the sum-rules are simulated for Fe, Co and Ni crystals with artificialy varied spin and orbital moments by means of the LDA + U method. These are then compared to directly calculated magnetic moments and found to be in close agreement. (C) 2007 Elsevier B.V. All rights reserved.
