Designing electronic magnetoelectric matter with organic quantum spin trimers
Yuko Hosokoshi, Christopher P. Aoyama, Zhuowei Zhang +17
Magnetoelectric (ME) phenomena are commonly driven by spin-lattice coupling. Here we demonstrate a different route based on frustrated quantum spin trimers that intrinsically inter…
Numerical Diagonalization Study of the Phase Boundaries of the S=2 Heisenberg Antiferromagnet on the Orthogonal Dimer Lattice
Hiroki Nakano, Toru Sakai, Yuko Hosokoshi
The S=2 Heisenberg antiferromagnet on the orthogonal dimer lattice is studied. The edges of the exact dimer and Neel-ordered phases in the ground state of the system are examined b…
Realization of a triangular spin necklace in a verdazyl-based Ni complex
Itsuki Shimamura, Risa Yagura, Takanori Kida +6
We successfully synthesized a verdazyl-based complex, (-Py-V)[Ni(NO)], in which Ni ions and verdazyl radicals form a one-dimensional, triangular spin necklace…
Magnetic-field-induced Tomonaga-Luttinger liquid and Bose-Einstein condensate phases in an organic S=1 Haldane chain
I. Jakovac, M. S. Grbić, M. Dupont +7
We present a comprehensive low-temperature H nuclear magnetic resonance (NMR) study of magnetic field-induced phases and spin fluctuations in an isotropic Haldane chain system…
Gapless behavior in a two-leg spin ladder with bond randomness
Yu Tominaga, Itsuki Shimamura, Takanori Kida +5
We successfully synthesized [Cu(AcO)(-Py-V--F)]4CHCl, a verdazyl-based complex with a paddlewheel structure comprising two Cu atoms, which induces stro…
Properties of an organic model Haldane chain system
Ivan Jakovac, Tonči Cvitanić, Denis Arčon +14
We present the properties of a new organic antiferromagnetic chain system -NOPhBNO (abbreviated BoNO). In this biradical system two unpaired electrons from aminoxyl gr…
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…
Field-induced incommensurate phase in the strong-rung spin ladder with ferromagnetic legs
H. Yamaguchi, H. Miyagai, M. Yoshida +12
We report magnetization, specific heat, and NMR measurements of 3-Br-4-F-V [=3-(3-bromo-4-fluorophenyl)-1,5-diphenylverdazyl], a strong-rung S=1/2 Heisenberg spin ladder with ferro…
Various regimes of quantum behavior in S = 1/2 Heisenberg antiferromagnetic chain with fourfold periodicity
H. Yamaguchi, T. Okubo, K. Iwase +7
We have succeeded in synthesizing single crystals of the verdazyl radical beta-2,6-Cl2-V [= beta-3-(2,6-dichlorophenyl)-1,5-diphenylverdazyl]. The ab initio MO calculation indicate…
