Abstract
Recently we have observed a small change in the width, sigma, of the Mn-O p air distribution function when a 1T magnetic field is applied. To improve o ur sensitivity to magnetic-field-induced changes, we have developed a magne tic field modulation technique. At each Xray energy we collect two data poi nts, one with field on and the other with field off; as a result we collect two scans simultaneously. The difference in these two traces provides a me asure of the magnetic-field- induced change. The results for the modulation measurements will be compared to the earlier work using static magnetic fi elds.
