Research Abstract

We measured the temperature dependences of magnetic susceptibility, thermal etpansion and magnetostriction of heaty termion compound CeRu2Si2 dotn to tt temperature region. We obserted the uncontentional behatior, suggesting that this compound is tery close to the Quantum Critical Point (QCO).
We also predicted the net QCP at higher pressure side for this compound.
