摘要: 本文报导了对非晶态铁磁合金F79B15.5S3.5C2样品的11B核磁共振自旋回波的测量结果。所得回波的形状既与射频场强度有关也与射频脉冲宽度有关。从理论上计算了几种条件下的回波波形。实验结果与计算结果基本符合。

Abstract: The 11BNMR spin echoes in amorphous ferromagnetic alloy Fe79B15.5 Si3.5C2 were measured. Their shapes were found to be dependent on both the strength of RF field and the width of the pulses, and compared with the calculated results. The agreement between the measured and calculated results was reasonably well.
