Heavy fermion quantum criticality at dilute carrier limit in CeNi${}_{2-\delta }$(As${}_{1-x}$P${}_x$)${}_2$

Jian Chen, Zhen Wang, Yupeng Li +5

We study the quantum phase transitions in the nickel pnctides, CeNi${}_{2-\delta }$(As${}_{1-x}$P${}_x$)${}_2$ ($\delta$ $\approx$ 0.07-0.22). This series displays the distinct heavy fermion beha…
