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 phases in a model S=1 Haldane chain system
I. Jakovac, M. S. GrbiÄ, M. Dupont +7
An Haldane chain is a one-dimensional (1D) quantum magnet where strong fluctuations result in quantum disordered singlet ground state with a gapped excitation spectrum. The g…
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, TonÄi CvitaniÄ, Denis ArÄon +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…
