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…
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…
Effect of crystallinity on spin-orbit torque in 5 iridium oxide IrO
Tetsuro Morimoto, Kohei Ueda, Junichi Shiogai +3
The 5 transition-metal oxides provide an intriguing platform for generating an efficient spin current due to a unique electronic structure dominated by 5d electrons wit…
Magnetic excitations from the hexagonal spin clusters in the S = 1/2 distorted honeycomb lattice antiferromagnet Cu2(pymca)3(ClO4)
Masaaki Matsuda, Alexander I. Kolesnikov, Zentaro Honda +4
Cu2(pymca)3(ClO4) (pymca: pyrimidine-2-carboxylate) consists of a slightly distorted honeycomb lattice of Cu2+ spins, which shows no long-range magnetic order down to 0.6 K. A magn…
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…
