We report the synthesis, structure and physical properties of a hitherto unreported brownmillerite compound Sr2ScFeO5. We have shown a new ordering sequence of the interlayer iron tetrahedral chains. Reduced dimensionality of the magnetic lattice and

We developed a new and environmentally friendly approach for recycling Ni–Cu-coated Nd–Fe–B permanent magnets included in computer hard disk drives collected as the waste of electrical and electronic equipment (WEEE). In a closed reactor, the c

International audience; The new iron layered oxysulfate Sr4Fe2.5O7.25(SO4)0.5 has been prepared by a solid-state reaction in closed ampules into the form of ceramics and single crystals. Its atomic structure has been solved by means of spectroscopy,

Publikováno v: Journal of Alloys and Compounds. 596:118-124

A granular Cu80Co20 alloy was elaborated by a low cost electrodeposition technique consisting in reducing simultaneously the Cu2+ and Co2+ ions onto a silicon substrate. The deposition parameters were determined from current-potential curves. The str
