Efficient launch of shear phonons in photostrictive halide perovskites
Dmytro Horiachyi, Mikhail O. Nestoklon, Ilya A. Akimov +10
Optical generation of transverse coherent phonons by femtosecond light pulses is appealing for high-speed sub-THz active control of material properties. Lead-free double perovskite…
Structural, magnetic, and nanoacoustic characterization of Co/Pt superlattices
E. R. Cardozo de Oliveira, C. Xiang, C. Borrazás +7
Superlattices presenting a spatial modulation of the elastic properties appear as a main tool to reach the THz regime in nanoacoustic devices. The exploration of alternative materi…
Nanostructured thin films of indium oxide nanocrystals confined in alumina matrixes
A. Bouifoulen, M. Edely, N. Errien +6
Nanocrystals of indium oxide (InO) with sizes below 10 nm were prepared in alumina matrixes by using a co-pulverization method. The used substrates such as borosilicate gla…
Nonlinear phononics in BiTe nanoscale thin films: A theoretical approach
A. Levchuk, R. Busselez, G. Vaudel +3
Density Functional Theory (DFT) calculations not only allow to predict the vibrational and optical properties of solids but also to understand and disentangle the mechanisms playin…
Dynamic control of ferroic domain patterns by thermal quenching
Jan Gerrit Horstmann, Ehsan Hassanpour, Yannik Zemp +3
Controlling the domain structure of ferroic materials is key to manipulating their functionality. Typically, quasi-static electric, magnetic, or strain fields are exploited to tran…
Restructuring disorder: Transformation from the antiferromagnetic order in Fe2VSi to the ferromagnetic state in FeRuVSi by substitution of a non-magnetic element
Shuvankar Gupta, Sudip Chakraborty, Celine Barreteau +4
The delicate nature of the half-metallic ferromagnetic (HMF) property in Heusler alloys is often compromised by inherent structural disorder within the systems. Fe2VSi is a prime e…
