"magnetic-superconducting hybrid systems enable topological superconductivity with potential applications in fault-tolerant quantum computing, but struggle with lattice mismatches/ complex interfacial interactions/ disorder, overcome with precise atomic-scale control over magnetic structures using sub-monolayer CrTe2/NbSe2 heterostructure... creates stripe-like patterns with edges hosting localized magnetic moments, effectively forming 1D magnetic chains... tunable periodic stress-induced structure"
