用非破坏性脉冲磁铁测量了在高达21 T的脉冲强磁场下的软X射线磁圆二色性。作为强磁场XMCD测量的一个例子，研究了Co 70 Fe 30/Mn 75 Ir 25双层膜中Co和MnL 2，3边的XMCD效应.采用总电子产额法检测吸收。吸收通过与50 ms高磁场脉冲同步的1 MHz时间分辨检测来记录。使用这种方法，XMCD效应由μ m（H）表示，这是磁场的函数。
Soft X-ray magnetic circular dichroism (XMCD) under pulsed high magnetic fields of up to 21 T has been measured using a nondestructive pulse magnet. XMCD effects at the Co and the Mn L 2, 3-edges of a Co 70 Fe 30/Mn 75 Ir 25 bilayer film have been investigated as an example of a high-magnetic-field XMCD measurement. A total electron yield method is adopted to detect absorption. Absorption is recorded by a 1-MHz time-resolved detection synchronized with a 50-ms high-magnetic-field pulse. Using this method, the XMCD effect is represented by µ m (H), a function of magnetic field.
