Temperature Dependence of Viscosity in Normal Fluid ${}^3$He Below 800mK Determined by a Micro-electro-mechanical Oscillator

M. Gonzalez, W. G. Jiang, P. Zheng +3

A micro-electro-mechanical system vibrating in its shear mode was used to study the viscosity of normal liquid ${}^3$He from 20mK to 770mK at 3bar, 21bar, and 29bar. The damping coef…
