Pyroelectric Effect and Ferroelectric Phase Transition in BixSb1-xSIntial difference across a short-circuiting resistance, while heating the samples at uniform rates. Critical temperature T. follows a rapid linear decrease when x increases up to 0.50, with a slope of 36 K per 0.10 Bi concentration.

Isotropic-Nematic Transition in Liquid Crystalshtly below T., the temperature at which the IN transition actually occurs. Using the temperature and frequency dependences of proton relaxation rates together with the general ideas on the scattering phenomena and nuclear relaxation arising from critical fluctuations in the order parameter, it is dePromotion 发表于 2025-3-28 05:17:18
Central Peak and Critical Dynamics of the Transverse Ising Model Above T C *ing model are investigated. Our investigation is based on the resolution of kinetic equations for the correlation functions derived beyond the random phase approximation. We complete previous work by considering a very general interaction made of dipole-dipole, anistropic nearest-neighbour and isotrExposure 发表于 2025-3-28 10:14:22

The analysis of the magnetic contribution to the birefringence demonstrates that some magnetic short-range order subsists till T..Angioplasty 发表于 2025-3-28 13:24:13
Spin Reorientation Transition in Gadoliniumnsition in Gd at T. = 223 K. We confirm the negligible role played by fluctuations, but our results imply new consequences on the validity of models to describe the angle of rotation (θ) between the magnetisation and the c-axis in Gd. Quite generally, ρ(θ) = ρ(-θ) from symmetry so that dρ/dT - θ.dθ/
