  Motivated by recent progress on quantum engineered Kondo lattices, we
numerically investigated the local magnetic properties of a hexagonal Anderson
droplet consisting of multiple rings of magnetic atoms periodically arrayed on
a triangular lattice. We demonstrated the tunability of the magnetic properties
via their evolution with the droplet geometry for two types of systems with
distinct local orbital occupancy profile. We found that the local
susceptibility of the droplet center of some types of droplets can be
remarkably enhanced in contrast to the conventionally rapid decrease due to
spin correlations of surrounding droplet rings. The tunability of the magnetic
properties is attributed to the charge redistribution with varying the droplet
geometry enforced by the confined lattice with open boundary. Our simulations
complements the exploration of the novel artificial tunability of engineered
lattice systems.
