摘要:

用中子衍射方法研究了YCo $_5$化合物在$0 \le p \le 7.2 \ GPa$压力范围内的晶体结构和磁性。结合密度泛函和动力学平均场论的结果对实验数据进行了分析。实验测定和计算值的钴力矩之间的一个很好的协议。我们的情况下的行为的YCo $_5$在压力下,是一个强的局部电子-电子相互作用的Lifshitz转变的组合作用。

英文摘要:

The crystal structure and magnetic properties of YCo$_5$ compound have been studied by neutron diffraction, in the pressure range $0 \le p \le 7.2 \ GPa$. The experimental data are analyzed together with results from the combined Density Functional and Dynamical Mean-Field Theory. A good agreement between the experimentally determined and calculated values of cobalt moments is shown. Our scenario for the behavior of YCo$_5$ under pressure, is the combined action of the Lifshitz transition with a strong local electron-electron interaction.
