continuous degeneracy, in which other factors must be taken into account in addition to the …

Ordering due to disorder in a frustrated vector antiferromagnet

CL Henley - Physical review letters, 1989 - APS
In many continuous spin systems, competing interactions give nontrivial degeneracies of the
classical ground states. Degeneracy-breaking free-energy terms arise from thermal (or …
