Quantum decoherence by magnetic fluctuations in a magnetic topological insulator
Single crystals of EuSn2As2, EuSn2P2, and the 1:1 alloy EuSn2AsP were prepared by a flux method similar to refs. 21,22. All three materials show similar nonlinear optical responses, and magnetic susceptibility measurements show clear signatures…

Solid gold superheated to 14 times its melting temperature
A cup of distilled water can sometimes be heated in a microwave for a long time without boiling, only to erupt explosively when the water is disturbed. This is an example of a phenomenon called superheating: the water is heated beyond its boiling…

Exploring the optical and electrical properties of CsSnBr3 for optoelectronic technologies
Figure 1 presents the PXRD pattern of the CsSnBr3 compound at 300 K, with diffraction peaks assigned to the cubic system \((P\overline{m}3m\;(221))\). Lattice parameters were refined using Celeref 3 software, yielding a value of a = 5.873…
