| Research Abstract |
We have performed ultrasonic measurements of elastic constant (C11-C12)/2 on URu2Si2 by using long-pulsed magnetic field up to 68.7 T at Dresden High Magnetic-field Laboratory in order to investigate the multipole ordering models which has recently been proposed to explain the unknown 'hidden order' parameter of this compound. The present results show that the c-f hybridized heavy-electron state of this compound accompanies 3-lattice instability, and also suggest that the both hybridization and the lattice instability disappears at high magnetic field region.
