Yttrium Iron Garnet Thin Films with Very Low Damping Obtained by Recrystallization of Amorphous Material [PDF]

Scientific Reports, 2015
We have investigated recrystallization of amorphous Yttrium Iron Garnet (YIG) by annealing in oxygen atmosphere. Our findings show that well below the melting temperature the material transforms into a fully epitaxial layer with exceptional quality, both

Stabilization of the Benzene Radical Trianion in an Inverse‐Sandwich Yttrium Complex

Angewandte Chemie, EarlyView.
A new type of benzene anion state is born: The unprecedented benzene radical trianion embedded in an inverse‐sandwich yttrium complex was synthesized by a one‐electron chemical reduction of its benzene dianion precursor using potassium graphite in the presence of [2.2.2]‐cryptand.

Design of a Cobalt‐Free Maraging Steel with Ultra‐High Strength of 2.3 GPa Through Additive Manufacturing

Advanced Science, EarlyView.
A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...

Electron paramagnetic resonance study of Ce doped partially stabilized ZrO2 crystals

Modern Electronic Materials, 2017
ZrO2 (PSZ) solid solutions crystals stabilized with yttrium and cerium oxides have been studied using electron paramagnetic resonance (EPR) in the X and Q ranges. Zr3+ have been observed centers in the as-annealed ZrO2 crystals stabilized only by yttrium
