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…
Emergence of Kondo-assisted Néel order in a Kondo necklace model
Hironori Yamaguchi, Shunsuke C. Furuya, Yu Tominaga +3
The interplay between Kondo screening and magnetic order has long been a central issue in the physics of strongly correlated systems. While the Kondo effect has traditionally been…
Experimental benchmark of the quantum-classical crossover in a spin ladder
Hironori Yamaguchi, Itsuki Shimamura, Akira Matsuo +4
We report a spin-(1/2, 5/2) three-leg ladder realized in a radical-Mn polymer, exhibiting an antiferromagnetic transition and magnetization curves accurately described by classical…
Realization of a Spin-1/2 Hexagonal-Plaquette Chain with Ising-Like Anisotropy
Hironori Yamaguchi, Shunsuke C. Furuya, Yu Tominaga +2
We present the realization of a spin-1/2 hexagonal-plaquette chain with Ising anisotropy, an unexplored quantum spin model that serves as a platform for investigating anisotropic q…
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…
