Rev. Lett. 101:065301, 2008). We have also shown the transition from the VF state into the supersolid (SS) state, which is characterized by a supersolid density and macroscopic coherence, below a transition (Kubota etal. in J. Low Temp. Phys. 158:572, 2010; Shimizu etal. in arXiv:0903.1326, 2009; Yagi etal. in J.Low Temp. Phys., QFS2010, 2011) atT c, as well as a critical velocity for the destruction of the SS state. Here we describe further confirming evidence of the phase transition into the SS state, namely, we report here some other observations than the hysteretic behavior. We find some other features which indicate a clear change of the properties in the hcp 4He below the same T c as hysteretic behavior, reported in Kubota etal. (J. Low Temp. Phys. 158:572, 2010), Shimizu etal. (arXiv:0903.1326, 2009), Yagi etal. (J.Low. Temp. Phys., QFS2010, 2011). It was discovered by detailed study of the torsional oscillator (TO) drive velocity V ac dependence of the nonlinear rotational susceptibility (NLRS) of the VF state. We discuss the features of the VF to SS transition. The large ratio between T o and T c may indicate large fluctuations of the system and it may give a basis for the vortex state (Fisher etal. in Phys. Rev. B 43(1):130, 1991) appearance in the hcp 4He, as seen in the new type of superconductors. We discuss a question related to the observation of the VF phase with specific dynamic features (Nemirovskii etal. in arXiv:0907.0330, 2009), coexisting with the SS phase and a possible new kind of phase transition coexisting with the SS phase and a possible new kind of phase transition for the VF to SS transition.
