Preferred Label : spin-Peierls transition;
IUPAC definition : A magneto-elastic transition that occurs in quasi one-dimensional antiferromagnetic
materials when the magnetic free energy decrease due to the formation of singlet spin
pairs outweighs the increase in lattice free energy occurring as a result of the dimerization
of the regular array. Example: The transition in tetrathiafulvalenium bis(dithiolene)cuprate
at 12 K.;
