Journal ArticleDOI
Superconductivity at 90 K in the Tl-Ba-Cu-O system.
TL;DR: Stable and reproducible superconductivity has been unambiguously observed in a new Tl-Ba-Cu-O system containing no group-IIIB elements and further substitutions of elements for this system may lead to even higher-temperature superconductors.
Journal ArticleDOI
Elasticity of lyotropic chromonic liquid crystals probed by director reorientation in a magnetic field.
Shuang Zhou,Yu. A. Nastishin,M. M. Omelchenko,Luana Tortora,V. G. Nazarenko,Oleksandr Boiko,T. Ostapenko,Tao Hu,Carmen Almasan,Samuel Sprunt,James T. Gleeson,Oleg D. Lavrentovich +11 more
TL;DR: Using a magnetic Frederiks transition technique, the temperature and concentration dependences of splay K1, twist K2, and bend K3 elastic constants for the lyotropic chromonic liquid crystal sunset yellow formed through noncovalent reversible aggregation of organic molecules in water are measured.
Journal ArticleDOI
Enhancement of flux pinning by Pr doping in Y 1 − x Pr x Ba 2 Cu 3 O 7 − δ (0≤ x ≤0.4)
TL;DR: Magnetic relaxation measurements in a magnetic field of 5 kOe at temperatures 5 K − 90 K have been made on the system as discussed by the authors, where the measurements reveal two peaks in the normalized logarithmic decay of the magnetization S as a function of temperature.
Journal ArticleDOI
Evidence for scaling invariance and universality of the irreversibility line of high temperature superconductors.

TL;DR: The results suggest that both the crossover phenomenon and the power law temperature dependence are ubiquitous, scale-invariant properties of high temperature superconductors.
Journal ArticleDOI
Metal-insulator transition above room temperature in maximum colossal magnetoresistance manganite thin films
Xiao-Jia Chen,Xiao-Jia Chen,H.-U. Habermeier,Haijun Zhang,G. Gu,Maria Varela,Jesus Santamaria,Carmen Almasan +7 more
TL;DR: In this article, Zhou et al. showed that a 50-layer thin film with a tolerance factor of 0.96 and a metal-insulator transition temperature above room temperature can achieve a doubling of the Jahn-Teller distortion.
