Tip-Angle-Dependent Magnetic Relaxation In Superfluid 3he, Richard A. Webb
Tip-Angle-Dependent Magnetic Relaxation In Superfluid 3he, Richard A. Webb
Faculty Publications
Using a pulsed superconducting-quantum-interference-device (SQUID) NMR technique, relaxation of the longitudinal magnetization in superfluid 3He has been measured in magnetic fields of 31, 102, 180, and 306 Oe in the pressure range 16-26 bar. It is observed that in both superfluid phases there is a temperature-dependent, well-defined spin-tipping angle, θc, for which the relaxation of the magnetization changes from an exponential to a nonexponential behavior.
