Kondo lattices with inequivalent local moments: Competitive versus cooperative Kondo screening
Kondo lattices with inequivalent local moments: Competitive versus cooperative Kondo screening
While standard heavy fermion metals feature a single spin-1/2 local moment per unit cell, more complicated systems with multiple distinct local moments have been synthesized as well, with Ce_3Pd_20(Si,Ge)_6 being one example. Here, we discuss the physics of a Kondo lattice model with two local-moment sublattices, coupled with different Kondo …
