摘要：

Recently we have observed a small change in the width, sigma, of the Mn-O pair distribution function when a 1T magnetic field is applied. To improve our sensitivity to magnetic-field-induced changes, we have developed a magnetic field modulation technique. At each Xray energy we collect two data points, 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 measure of the magnetic-field- induced change. The results for the modulation measurements will be compared to the earlier work using static magnetic fields.
