ISBN 978-0080570464. Lev D. Landau (1937). In a simple ferromagnetic system like the Ising model, the order parameter is characterized by the net magnetization m, which becomes spontaneously non-zero below a critical temperature \( T_{c} \). In Mukhamel's analysis of the isotropic Lifschitz point, the critical dimension is 8. 0000050720 00000 n

Furthermore, the order parameter follows the relation, \( {\displaystyle \eta (T)\propto \left|T-T_{c}\right|^{1/2}} \). which is reminiscent of the Curie-Weiss law for the temperature dependence of magnetic susceptibility in magnetic materials, and yields the mean-field critical exponent \( \gamma=1 \) . Kramers recognizes that phase transitions require an inﬁnite system. This order parameter is a measure of the order before and after a phase transition; the order parameter is often zero above some critical temperature and non-zero below the critical temperature.

To further demonstrate that the transition is first-order, one can show that the free energy for this order parameter is continuous at the transition temperature \( T_{*} \) , but its first derivative suffers from a discontinuity. 0000002203 00000 n
