Impact of the surface phase transition on magnon and phonon excitations in BiFeO3 nanoparticles
Ian Aupiais, Pierre Hemme, Marc Allen +8
We have performed Raman scattering measurements on BiFeO3 nanoparticles and studied both magnetic and lattice modes. We reveal strong anomalies between 140 K and 200 K in the frequ…
Intrinsic Photon Loss at the Interface of Superconducting Devices
Igor Diniz, Rogério de Sousa
We present a quantum theory of dielectric energy loss arising from the piezoelectric coupling between photons and phonons in superconducting devices. Photon loss is shown to occur…
Size-dependent bistability in multiferroic nanoparticles
Marc Allen, Ian Aupiais, Maximilien Cazayous +1
Most multiferroic materials with coexisting ferroelectric and magnetic order exhibit cycloidal antiferromagnetism with wavelength of several nanometers. The prototypical example is…
Impact of nonlocal electrodynamics on flux noise and inductance of superconducting wires
Pramodh Senarath Yapa, Tyler Makaro, Rogério de Sousa
We present exact numerical calculations of supercurrent density, inductance, and impurity-induced flux noise of cylindrical superconducting wires in the nonlocal Pippard regime, wh…
