d0 Ferromagnetism in Ag-doped Monoclinic ZrO2 Compounds
L. Chouhan, G. Bouzerar, S. K. Srivastava
Recently d0 or intrinsic ferromagnetism was believed to provide an alternative pathway to transition metal induced ferromagnetism in oxide. In pursuit of augmenting the area of d0…
Epitaxial Ferroelectric La-doped Hf0.5Zr0.5O2 Thin Films
Tingfeng Song, Romain Bachelet, Guillaume Saint-Girons +3
Doping ferroelectric Hf0.5Zr0.5O2 with La is a promising route to improve endurance. However, the beneficial effect of La on the endurance of polycrystalline films may be accompani…
Out-of-equilibrium Polymorph Selection in Nanoparticle Freezing
Jonathan Amodeo, Fabio Pietrucci, Julien Lam
The ability to design synthesis processes that are out of equilibrium has opened the possibility of creating nanomaterials with remarkable physico-chemical properties, choosing fro…
Wurtzite phase control for self-assisted GaAs nanowires grown by molecular beam epitaxy
T. Dursap, M. Vettori, C. Botella +7
The accurate control of the crystal phase in III-V semiconductor nanowires (NWs) is an important milestone for device applications. In this work, we present a method to select and…
Low thermal conductivity of iron-silicon alloys at Earth core conditions with implications for the geodynamo
Wen-Pin Hsieh, Alexander F. Goncharov, Stéphane Labrosse +5
Earth core is composed of iron (Fe) alloyed with light elements, e.g., silicon (Si). Its thermal conductivity critically affects Earth thermal structure, evolution, and dynamics, a…
Structural and lattice-dynamical properties of Tb2O3 under compression: a comparative study with rare-earth and related sesquioxides
Jordi Ibáñez, Juan Ángel Sans, Vanesa Cuenca-Gotor +9
We report a joint experimental and theoretical investigation of the high-pressure structural and vibrational properties of terbium sesquioxide (Tb2O3). Powder x-ray diffraction and…
