Observation of thermodynamics originating from a mixed-spin ferromagnetic chain
H. Yamaguchi, S. C. Furuya, S. Morota +6
We present a model compound that forms a mixed-spin ferromagnetic chain. Our material design, based on the organic radicals, affords a verdazyl-based complex (p-Py-V)2[Mn(hfac)2].…
Gapped ground state in a spin-1/2 frustrated square lattice
H. Yamaguchi, N. Uemoto, T. Okubo +7
We present a model compound with a spin-1/2 frustrated square lattice, in which three ferromagnetic (F) interactions and one antiferromagnetic (AF) compet. Considering the effectiv…
Quantum critical phenomena in a spin-1/2 frustrated square lattice with spatial anisotropy
H. Yamaguchi, Y. Iwasaki, Y. Kono +7
We present a model compound with a spin-1/2 spatially anisotropic frustrated square lattice, in which three antiferromagnetic interactions and one ferromagnetic interaction are com…
Experimental realization of Lieb-Mattis plateau in a quantum spin chain
H. Yamaguchi, T. Okita, Y. Iwasaki +7
We present a mixed spin-(1/2, 5/2) chain composed of a charge-transfer salt (4-Br--MePy-V)FeCl. We observe the entire magnetization curve up to saturation, which exhibits a…
Emergent critical phenomenon in spin-1/2 ferromagnetic-leg ladders: Quasi-one-dimensional Bose--Einstein condensate
Y. Kono, S. Kittaka, H. Yamaguchi +2
We examine the magnetic-field-induced criticality of phase boundary near saturation field in the spin-1/2 ferromagnetic (FM)-leg ladder 3-Cl-4-F-V [=3-(3-chloro-4-…
=1/2 ferromagnetic Heisenberg chain in a verdazyl-based complex
N. Uemoto, Y. Kono, S. Kittaka +6
We present a model compound for the =1/2 ferromagnetic Heisenberg chain composed of the verdazyl-based complex Zn(hfac)4-Cl--Py-V-(4-F). MO calc…
