Tailored topotactic chemistry unlocks heterostructures of magnetic intercalation compounds
arxiv(2024)
摘要
The construction of thin film heterostructures has been a widely successful
archetype for fabricating materials with emergent physical properties. This
strategy is of particular importance for the design of multilayer magnetic
architectures in which direct interfacial spin–spin interactions between
magnetic phases in dissimilar layers lead to emergent and controllable magnetic
behavior. However, crystallographic incommensurability and atomic-scale
interfacial disorder can severely limit the types of materials amenable to this
strategy, as well as the performance of these systems. Here, we demonstrate a
method for synthesizing heterostructures comprising magnetic intercalation
compounds of transition metal dichalcogenides (TMDs), through directed
topotactic reaction of the TMD with a metal oxide. The mechanism of the
intercalation reaction enables thermally initiated intercalation of the TMD
from lithographically patterned oxide films, giving access to a new family of
multi-component magnetic architectures through the combination of deterministic
van der Waals assembly and directed intercalation chemistry.
