Abstract

The effects of static disorder in unconventional superfluid 3He were investigated. Shear acoustic impedance measurements were performed on this system in the presence of magnetic fields upto 15 T at the sample pressures of 28.4 and 33.5 bars. The splitting of the superfluid transition into two transition in high fields in both bulk and liquid in aerogel was observed. It was found that the field dependence of each transition was consistent with that of the A1m phase observed in pure liquid with a reduced strong coupling effect.
