| Popis: | We performed ultrasonic and temperature measurements under pulsed magnetic fields on CeIrIn$_5$ to investigate whether or not the origin of metamagnetic transition and field-induced Lifshitz transition was described by the anisotropic electronic ordering with crystal symmetry breaking. We observed elastic anomalies with the negative magnetocaloric effects around the field-induced Lifshitz transition and the metamagnetic transition. On the other hand, the elastic anomalies appeared both in the transverse elastic constants $(C_{11} - C_{12})/2$ and $C_{66}$ in CeIrIn$_5$ while $(C_{11} - C_{12})/2$ showed significant elastic anomaly at the crystal symmetry breaking fields in CeRhIn$_5$. These results indicate that the anisotropic electronic ordering with crystal symmetry breaking is absent in high-magnetic fields in CeIrIn$_{5}$. 6 pages, 2 figures, Accepted in JPS Conf. Proc.
