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…

Diamond chains with multiple-spin exchange interactions
N. B. Ivanov, J. Richter, J. Schulenburg
We study the phase diagram of a symmetric spin-1/2 Heisenberg diamond chain with additional cyclic four-spin exchange interactions. The presented analysis supplemented by numerical…
