Spin-Peierls transition to a Haldane phase

Hironori Yamaguchi, Hiroki Takahashi, Takashi Kawakami +4

We present an organic compound exhibiting a spin-Peierls (SP) transition to an effective spin-1 antiferromagnetic uniform chain, that is, the Haldane chain. The clear disappearance…

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- $o$ -MePy-V)FeCl $_{4}$ . We observe the entire magnetization curve up to saturation, which exhibits a…

Field-induced quantum magnetism in the verdazyl-based charge-transfer salt $[$ $o$ -MePy-V-( $p$ -Br) $_{2}]$ FeCl $_{4}$

Y. Iwasaki, T. Kida, M. Hagiwara +6

We successfully synthesized a verdazyl-based charge-transfer salt $[$ $o$ -MePy-V-( $p$ -Br) $_{2}]$ FeCl $_{4}$ , which has an $S_{V}$ =1/2 on the radical $o$ -MePy-V-( $p$ -Br) $_{2}$ and an $…

Anomalous magnetization of $S$ =2 ferromagnetic-antiferromagnetic alternating chain with Ising anisotropy

H. Yamaguchi, Y. Shinpuku, Y. Kono +7

We present the first experimental realization of an $S = 2$ ferromagnetic-antiferromagnetic (F-AF) alternating chain in a new Mn-verdazyl complex [Mn(hfac) $_{2}$ ] $\cdot$ ( $o$ -Py-V) [hfa…

Fine-Tuning of Magnetic Interactions in Organic Spin Ladders

Hironori Yamaguchi, Hirotsugu Miyagai, Tokuro Shimokawa +10

We have succeeded in synthesizing two types of new organic radical crystals 3-I-V [= 3- (3-iodophenyl)-1,5-diphenylverdazyl] and 3-Br-4-F-V [= 3-(3-bromo-4-fluorophenyl)-1,5- diphe…
