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…
=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…
Field-induced quantum magnetism in the verdazyl-based charge-transfer salt -MePy-V-(-Br)FeCl
Y. Iwasaki, T. Kida, M. Hagiwara +6
We successfully synthesized a verdazyl-based charge-transfer salt -MePy-V-(-Br)FeCl, which has an =1/2 on the radical -MePy-V-(-Br) and an $…
Field-enhanced quantum fuctuation in S=1/2 frustrated square lattice
H. Yamaguchi, Y. Sasaki, T. Okubo +9
We present a new model compound with the S = 1/2 frustrated square lattice composed of the charge-transfer salt (o-MePy-V)PF6. Ab initio calculations indicate the formation of an S…
