TL;DR: In this article, the magnetic and electronic phase diagram of β-Fe1.01Se has been analyzed and the transition temperature increases from 8.5 to 36.7 K under an applied pressure of 8.9 GPa.

TL;DR: In this article, the superconductivity transition temperature in beta-Fe1.01Se increases from 8.5 to 36.7 K under applied pressure of 8.9 GPa.

TL;DR: In this article, it was shown that superconductivity in Fe1+?Se, which can be considered the parent compound of the superconducting arsenide family, is destroyed by very small changes in stoichiometry.

TL;DR: In this article, a simple concept was used for a systematic search for materials with high spin polarization, based on two semi-empirical models: the Slater-Pauling rule was used to estimate the magnetic moment and the second model was found particularly for Heusler compounds when comparing their magnetic properties.

TL;DR: High resolution electron microscopy at low temperatures further reveals an unexpected additional modulation of the crystal structure of the superconducting phase that involves displacements of the Fe atoms, and that the nonsuperconducting composition shows a different, complex nanometer-scale structural modulation.
