Abstract

Using an R-F biased SQUID, the temperature dependent susceptibility of superfluid 3He-B has been measured both statically and via a pulse technique in a field of 309 gauss and in a pressure range 26.5 to 18 bar. In 3He-B the dynamic susceptibility as determined using pulsed SQUID NMR agrees with the theoretical predictions for the BW state. However, the static susceptibility measured, using the same R-F biased SQUID and pick up coil, is significantly smaller than the dynamic susceptibility.
