Viscosity measurements in pulsed magnetic fields by using a quartz-crystal microbalance
Nomura, T.; Zherlitsyn, S.; Kohama, Y.; Wosnitza, J.;
Viscosity measurements in combination with pulsed magnetic fields are developed by use of a quartz-crystal microbalance (QCM). When the QCM is immersed in liquid, the resonant frequency, f0, and the quality factor, Q, of the QCM change depending on (pn)0.5, where p is the mass density and n the viscosity. During the magnetic-field pulse, f0 and Q of the QCM are simultaneously measured by a ringdown technique. The typical resolution of (pn)>sup>0.5 is 0.5%. As a benchmark, the viscosity of liquid oxygen is measured up to 55 T.
