Non-Griffiths-like cluster formation in the double-perovskite Gd 2 CoMnO 6 : Evidence from critical behavior
TL;DR: In this article, the Yang-Lee theory of phase transition predicts that the essential singularity of the Griffiths phase leads to very unusual critical phenomena, including a discontinuity in the magnetization isotherm at $T =T}_{C}$, which is reflected through the large value of critical exponent $\ensuremath{\delta}$.

Anharmonic effects in light scattering due to optical phonons in silicon
TL;DR: In this paper, light scattering of the linewidth and frequency shift of the optical phonon in silicon over the temperature range of 5-1400 K are presented. But they do not consider the four-phonon anharmonic processes.
Journal ArticleDOI
Nonanalytic Behavior Above the Critical Point in a Random Ising Ferromagnet
TL;DR: In this paper, it was shown that in a class of randomly diluted Ising ferromagnets the magnetization fails to be an analytic function of the field at a range of temperatures above that at which spontaneous magnetization first appears.
