A new superfluid phase of ³He, a polar phase, which is known to stabilize in nematic aerogel, has already led to the observation of many new phenomena. One important condition for the existence of the polar phase is a ⁴He coverage, which removes solid paramagnetic ³He from the surface of the aerogel strands. We report here the results of NMR experiments with superfluid ³He in nematic aerogel demonstrating the influence of ⁴He coverage. Simultaneous measurements of resonance properties of a quartz tuning fork immersed in liquid ³He well correlate with the NMR data.
