论文摘要
我们在CEIRIN $ _5 $上进行了超声波和温度测量，以研究元磁过渡的起源和野外诱导的LIFSHITTINTION是否通过各向异性电子订购和晶体对称性破裂描述。我们观察到弹性异常，具有磁场诱导的LIFSHITTITION和元磁转变周围具有负磁性作用。 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$_5$.这些结果表明，在CEIRIN $ _ {5} $的高磁场中，不存在与晶体对称性破裂的各向异性电子订购。
We performed ultrasonic and temperature measurements under pulsed magnetic fields on CeIrIn$_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$_{5}$.
