“…The asymmetry ratios are also listed in Table I where r a ÿT aA1 ÿ T ac =T aA2 ÿ T ac and T ac is zero field bulk (aerogel) transition temperature. The bulk slopes and r are in good agreement with previous measurements within 8% [15,17]. It is notable that there is no appreciable difference in the A 1 slopes for the bulk and aerogel, which is consistent with the theory of Sauls and Sharma.…”

“…The vibrating wire measurement was done in a similar fashion as described in Ref. [17] and the amplitude of the resonance is shown in the figure. Two sharp cusps in the VW trace correspond to the A 1 and A 2 transitions in pure liquid as reported in a previous work [17].…”

“…[17] and the amplitude of the resonance is shown in the figure. Two sharp cusps in the VW trace correspond to the A 1 and A 2 transitions in pure liquid as reported in a previous work [17]. These features are concurrent with the jumps in the acoustic trace.…”

“…The pressure offsets for all fields (including zero field) are around 6 kPa within 10%. The temperature width of the A 1 phase was obtained using the results from Sagan et al [15] and Remeijer et al [17]. By using the A 1 width rather than the actual transition temperature as a fixed point, we can circumvent the possible inconsistency in the absolute temperature scale used in the previous work.…”

“…50) The A 1 transition temperatures, T c1 and T c2 , were measured by the vibrating wire viscometer techniques 6) up to 15 and 12 T, respectively, at the melting pressure. 52) These are the highest static fields to have been applied to produce A 1 phase to date. The linear dependence of the transition temperatures on magnetic field was consistent with other experiments as well as theory.…”
