Frustrated spin ladder with alternating spin-1 and spin-1/2 rungs
V. Ravi Chandra, N. B. Ivanov, J. Richter
We study the impact of the diagonal frustrating couplings on the quantum phase diagram of a two-leg ladder composed of alternating spin-1 and spin-1/2 rungs. As the coupling streng…

Spin models of quasi-1D quantum ferrimagnets with competing interactions
N. B. Ivanov
We present a brief survey of the recent theoretical work related to generic Heisenberg spin models describing quasi-one-dimensional quantum ferrimagnets. The emphasis is on quantum…
