According to hydrodynamic, acoustic, and NMR studies the superfluid transition temperature of 3He in aerogel ( Tca) is significantly suppressed with respect to that of bulk 3He. We have found in the range of temperatures between Tc and Tca a large and unexpected NMR satellite line attributable to the liquid inside the aerogel. We propose that this anomalous behavior of liquid 3He corresponds to a new type of superfluid ordering related to magnetic and possibly orbital coherence.
