  Despite extensive research on magnetic skyrmions and antiskyrmions, a
significant challenge remains in crafting nontrivial high-order skyrmionic
textures with varying, or even tailor-made, topologies. We address this
challenge, by focusing on a construction pathway of skyrmionics metamaterial
within a monolayer thin film and suggest several promising lattice-like,
flakes-like, and cell-like skyrmionic metamaterials that are surprisingly
stable. Central to our approach is the concept of 'simulated controlled
assembly', in short, a protocol inspired by 'click chemistry' that allows for
positioning topological magnetic structures where one likes, and then allowing
for energy minimization to elucidate the stability. Utilizing high-throughput
atomistic-spin-dynamic (ASD) simulations alongside state-of-the-art AI-driven
tools, we have isolated skyrmions (topological charge Q=1), antiskyrmions
(Q=-1), and skyrmionium (Q=0). These entities serve as foundational 'skyrmionic
building blocks' to forming reported intricate textures. In this work, two key
contributions are introduced to the field of skyrmionic systems. First, we
present a novel method for integrating control assembly protocols for the
stabilization and investigation of topological magnets, which marks a
significant advancement in the ability to explore new skyrmionic textures.
Second, we report on the discovery of skyrmionic metamaterials, which shows a
plethora of complex topologies that are possible to investigate theoretically
and experimentally.
