Imaging magnetic order in magneto-structural phases of Mn3O4
… complex lattice geometry, strong spin-lattice coupling and magnetic interactions. Mn3O4 is known to have two distinct phases below the Neel temperature that differ in both structure and magnetic order, including a tetragonal phase with disordered spins, and at lower temperatures, an …

CHARACTERIZATION AND MODELLING OF MAGNETO-AUXETICITY, THE MAGNETICALLY INDUCED AUXETIC BEHAVIOR, IN GALFENOL
Iron-Gallium alloy (Galfenol) is a magnetostrictive smart material (λsat ~400 ppm) with potential for robust transduction owing to good magneto-mechanical coupling and useful mechanical properties. In addition, Galfenol exhibits a highly negative Poisson’s ratio (denoted by ν) along the <110> …

Elasticity measurements at extreme conditions: application to FeO and FeNi-alloy
… requires the knowledge of fully anisotropic elasticity data for mineral phases. The single-crystal elastic constants of minerals, Cij, are elements of the fourth-rank elasticity tensor, which relates stress to strain. The fact that elastic strain also defines seismic wave propagation, the …

TIME RESOLVED PROBING OF MAGNETO-ELASTIC EXCITATIONS IN MAGNETIC MATERIALS
… My experimental activity addressed the coupling of magnetic and acoustic degrees of freedom in transition-metal ferromagnetic systems. Within the NFFA-SPRINT laboratory, hosted in the premises of the facility FERMI@Elettra (Elettra-Sincrotrone Trieste), I developed a setup to perform …
