Quantum critical point followed by Kondo-like behavior due to Cu substitution in itinerant, antiferromagnet ${\text{La}}_2{\text{(Cu}}_x{\text{Ni}}_{1-x}{)}_7$

Atreyee Das, Siham Mohamed, Raquel A. Ribeiro +5

${\text{La}}_2{\text{Ni}}_7$ is an itinerant magnetic system with a small ordered moment of $\sim$ 0.1 ${\mu }_B/\text{Ni}$ and a series of antiferromagnetic (AFM) transitions at $T_1$ =…
