Abstract

The microscopic origin of the low-field 1/9 magnetization plateau in spin-1/2 kagome antiferromagnets remains unresolved. Here, we show that chemical pressure reshapes the hierarchy of fractional magnetization plateaus in the titanium-based kagome family Cs8AB3Ti12F48 (A=Rb,Li; B=K,Na). High-field magnetization measurements up to 60 T reveal a robust 1/9 plateau-like phase in the expanded Cs8RbK3Ti12F48 and Cs8LiK3Ti12F48 compounds, despite the absence of the conventionally more robust 1/3 plateau. In contrast, compressed Cs8LiNa3Ti12F48 exhibits neither the 1/9 plateau-like phase nor a quantum-disordered ground state. Specific-heat measurements and first-principles calculations show that lattice expansion preserves a frustrated, fully connected kagome exchange network and gapless quantum-disordered ground states, whereas compression reorganizes the exchange network into weakly coupled quasi-one-dimensional subsystems and induces successive magnetic transitions. These results demonstrate that the 1/9 and 1/3 plateaus need not share a common microscopic origin and suggest that the 1/9 plateau may represent a more universal feature of frustrated spin-1/2 kagome magnetism.
