The nuclear spin-lattice relaxation rate 1/T1 of the 59Co NMR in ferromagnetic Co monotonically decreases with increasing field, approaching a constant value for H > 4φM. The high field rate is in semi-quantitative agreement with previous theoretical calculations. Similar results are found for 61Ni in Ni and 55Mn for Mn impurities in Fe.

59Co在铁磁Co中的核自旋-晶格弛豫速率1/T1随磁场的增加而单调减小，在H >下趋于恒定值;4 Mφ。高场强与以往的理论计算结果半定量一致。在Ni中发现了61Ni杂质，在Fe中发现了55Mn杂质。

In response to a small low-frequency a.c. field superimposed upon a large d.c. field, small flux jumps are observed to occur only during the half cycle corresponding to flux flowing out of a type II superconductor when in the mixed state. An explanation is proposed based on the thermal effects of the flow, creation and annihilation of flux vortices.

当一个小的低频交流场叠加在一个大的直流场上时，观察到只有在与II型超导体在混合状态下流出的通量相对应的半周期内才会出现小的磁通跳变。从通量涡的流动、产生和湮灭的热效应出发，提出了一种解释。
