In particular, at a high enough temperature, antiferroelectricity disappears; this temperature is called the "'antiferroelectric Curie point "', even though in the analogous antiferromagnetism this transition occurs at the Neel temperature

He has contributed substantially to spectroscopy on the magnetism of disordered systems and on high-temperature superconductors and antiferromagnetism identifying magnets with tuneable quantum fluctuations that can be used to study the transition between classical and quantum behavior.

Lattice models with nearest-neighbor interactions have been used extensively to model a wide variety of systems and phenomena, including the lattice gas, binary liquid solutions, order-disorder phase transitions, ferromagnetism, and antiferromagnetism.

"' Philip Warren Anderson "'( born December 13, 1923 ) is an localization, antiferromagnetism, symmetry breaking, and high-temperature superconductivity, and to the philosophy of science through his writings on emergent phenomena.

The " singlet state ", i . e . the " sign, means : the spins are " antiparallel ", i . e . for the solid we have antiferromagnetism, and for two-atomic molecules one has diamagnetism.
