Field-induced quantum phase in a frustrated zigzag-square lattice
PHYSICAL REVIEW MATERIALS(2023)
Abstract
This study presents the experimental realization of a spin-1/2 zigzag-square lattice in a verdazyl-based complex, namely (m-Py-V-2, 6-F2)[Cu(hfac)2]. Molecular orbital calculations suggest the presence of five types of frustrated exchange couplings. Our observations reveal an incremental increase in the magnetization curve beyond a critical field, signifying a phase transition from the antiferromagnetic ordered state to a quantum state characterized by a 1/2 plateau. This intriguing behavior arises from the effective stabilization of a zigzag chain by the external fields. These results provide evidence for field-induced dimensional reduction in a zigzag-square lattice attributed to the effects of frustration.
