DOI: 10.1016/j.jeurceramsoc.2021.06.014
Abstract: Abstract Entropy-stabilized oxides (ESO) display a reversible entropy-driven phase transformation that can be leveraged to produce a continuum of metastable phase states, allowing for property optimization and novel functionalities. X-ray absorption spectroscopy reveals that entropic… read more here.

DOI: 10.1016/j.scriptamat.2019.12.027
Abstract: Abstract Entropy stabilization was attempted through the addition of 5 different rare earth cations, 5 different transition metal cations and all these 10 cations in the form of three compounds based on NiFe2O4. Equiatomic ratios… read more here.
