Trilinear coupling and toroidicity in multiferroics
Andrea Urru, Alessio Filippetti, Jorge Íñiguez-Gonzàlez +1
Magnetoelectric responses are related in general to magnetic multipoles, and in particular the off-diagonal linear response is proportional to the toroidization order parameter. In…
Strain-induced magnetization control in an oxide multiferroic heterostructure
Federico Motti, Giovanni Vinai, Aleksandr Petrov +6
Controlling magnetism by using electric fields is a goal of research towards novel spintronic devices and future nano-electronics. For this reason, multiferroic heterostructures at…
A three-order-parameter bistable magnetoelectric multiferroic metal
Andrea Urru, Francesco Ricci, Alessio Filippetti +2
Using first-principles calculations we predict that the layered-perovskite metal BiMnO is a ferromagnet, ferroelectric, and ferrotoroid which may realize the long so…
Theory of thermoelectricity in MgSb with an energy- and temperature-dependent relaxation time
Roberta Farris, Maria Barbara Maccioni, Alessio Filippetti +1
We study the electronic transport coefficients and the thermoelectric figure of merit ZT in -doped MgSb based on density-functional electronic structure and Bloch-Boltzm…
Meta-screening and permanence of polar distortion in metallized ferroelectrics
Hong Jian Zhao, Alessio Filippetti, Carlos Escorihuela-Sayalero +5
Ferroelectric materials are characterized by a spontaneous polar distortion. The behavior of such distortions in the presence of free charge is the key to the physics of metallized…
Charge doping and large lattice expansion in oxygen-deficient heteroepitaxial WO3
Giordano Mattoni, Alessio Filippetti, Nicola Manca +2
Tungsten trioxide is a versatile material with widespread applications ranging from electrochromic and optoelectronic devices to water splitting and catalysis of chemical reactions…
