Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain
Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain
We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-field low-temperature properties. More specifically, in our study we assume that the partition function for a slightly distorted geometry has the same form as …
