Magnetic Field versus Temperature Phase Diagram of the Spin-1/2 Alternating Chain Compound F5PNN
Yasuo Yoshida, Tatsuya Kawae, Yuko Hosokoshi +5
We have measured the specific heat of the S = 1/2 alternating Heisenberg antiferromagnetic chain compound pentafluorophenyl nitronyl nitroxide in magnetic fields using a single cry…

Ground State Properties of an S=1/2 Distorted Diamond Chain
Takashi Tonegawa, Kiyomi Okamoto, Toshiya Hikihara +2
We investigate the ground state properties of an S=1/2 distorted diamond chain described by the Hamiltonian ${\cal H}=J_1\sum_\ell\bigl\{\bigl(\vecS_{3\ell-1}\cdot\vecS_{3\ell} +\v…

Dimer Correlarions in Spin-1/2 Alternating XY Chain
Yohei Saika, Kiyomi Okamoto
We investigate the long-distance asymptotic behavior of the dimer correlations in the spin-1/2 alternating chain both at T=0 and at sufficiently low-temperatures. The correlati…
