We present results from a study of the nonlinear inter-modal coupling between different flexural vibrational modes of a single high-stress, doubly-clamped silicon nitride nanomechanical beam. Using the magnetomotive technique and working at 100 mK we

Measurements of the attenuation and velocity of pulsed high-frequency sound have been performed up to 133 MHz in superfluid $^{3}\mathrm{He}$-$B$. A new collective mode of the order parameter was discovered at a frequency extrapolated to ${T}_{c}$ of

We present the design of a versatile rf heterodyne spectrometer covering a 100 kHz to 190 MHz frequency range, which has been useful in nuclear magnetic resonance and acoustic experiments over its whole range. Commercial instruments were used whereve

The group velocity of high-frequency sound for $T\ensuremath{\ll}{T}_{c}$, and the group velocity and attenuation of sound at higher temperatures, have been measured and analyzed to give the frequencies and coupling strengths of two order-parameter c

Continuous-wave nuclear magnetic resonance measurements have been performed on liquid $^{3}\mathrm{He}$-$^{4}\mathrm{He}$ mixtures of 5.0% (at 0, 10, and 20 bars) and 9.5% (at 10 bars) $^{3}\mathrm{He}$ between 0.3 and 25 mK. In the collisionless reg
