Suppression of acoustic emission during superelastic tensile cycling of polycrystalline NiTi
Guillaume F. Nataf, Michela Romanini, Eduard Vives +4
We investigate acoustic emission (AE) that arises during the martensitic transition in a polycrystalline specimen of the prototypical superelastic/elastocaloric alloy NiTi…
High-contrast imaging of 180° ferroelectric domains by optical microscopy using ferroelectric liquid crystals
Guillaume. F. Nataf, Mael Guennou, Giusy Scalia +3
Ferroelectric liquid crystals (FLCs) couple the direction of their spontaneous electric polarization to the direction of tilt of their optic axis. Consequently, reversal of the ele…
Raman signatures of ferroic domain walls captured by principal component analysis
Guillaume F. Nataf, Nick Barrett, Jens Kreisel +1
Ferroic domain walls are currently investigated by several state-of-the art techniques in order to get a better understanding of their distinct, functional properties. Here, Princi…
Experimental evidence of accelerated seismic release without critical failure in acoustic emissions of compressed nanoporous materials
Jordi Baró, Karin A. Dahmen, Jörn Davidsen +5
The total energy of acoustic emission (AE) events in externally stressed materials diverges when approaching macroscopic failure. Numerical and conceptual models explain this accel…
Control of surface potential at polar domain walls in a nonpolar oxide
G. F. Nataf, M. Guennou, J. Kreisel +8
Ferroic domain walls could play an important role in microelectronics, given their nanometric size and often distinct functional properties. Until now, devices and device concepts…
