The Ph.D is in the frame of a Horizon 2020 Marie Sklodowska-Curie Innovative Training Network (acronym : BeMagic).

Title : Electric field contro of magnetisation reversal in multiferroic topological nanostructures for low-power magnetoelectronics and ultra-secure data devices

Objectives : Growth of multiferroic heterostructures (e.g., Fe80Ga20 in top of Pb(ZrxTi1-x)O3 or BaTiO3) by sputtering; top-

down and bottom-up nanolithography to obtain small disks and other sub-micrometric geometries of this material; assessment of the magnetization reversal mechanisms (vortex versus coherent rotation, i.

e., ON-OFF remanent magnetization) using local MOKE measurements and MFM observations; change of reversal mechanism applying electric field impulses using a customized AFM tip.

Expected results : Growth and patterning of ME heterostructures for data security devices; control of nucleation / annihilation (and displacement) of the curled topological magnetization structures as a function of electrical voltage.

Main outcome : scientific publications, instrumentation development, conferences and outreach.

During the PhD, secondments in private companies is scheduled so that, besides fundamental research in materials science aspects, the candidate will also acquire the very much needed know-

how on technological applications in diverse industrial sectors.

The selection process will be in two steps : a) sending a CV by e-mail to the INRIM supervisor and b) telematics interview (Skype)
