    Stacking Fault Energy in 4He Crystals

    Recently observed non-classical rotational inertial (NCRI) in solid 4He is most probably related to defects which appear during the sample preparation. We have measured the energy of the stacking fault (SF) in an...

    Elementary Excitations in Solid and Liquid 4He at the Melting Pressure

    Recent discovery of a nonclassical rotational inertia (NCRI) in solid 4He below 0.2 K by Kim and Chan has revived great interest in the problem of supersolidity and initiated intensive study on the properties of...

    Effect of the Magnetic Order on 3He Crystals

    Solid 3He orders magnetically into two different phases below the Néel transition depending on the magnetic field (U2D2 or low field phase below 450 mT and CNAF or high field phase above 450 mT). We have perform...
