Magnetic properties of the $S=1/2$ distorted diamond chain at T=0

Kiyomi Okamoto, Takashi Tonegawa, Makoto Kaburagi

We explore, at T=0, the magnetic properties of the $S=1/2$ antiferromagnetic distorted diamond chain described by the Hamiltonian ${\cal H} = \sum_{j=1}^{N/3}{J_1 ({\bi S}_{3j-1} \…
