Inhomogeneity-driven multiform Spontaneous Hall Effect in conventional and unconventional superconductors
Nadia Stegani, Ilaria Pallecchi, Nicola Manca +10
The spontaneous Hall effect (SHE), a finite voltage occurring transversal to the electrical current in zero-magnetic field, has been observed in both conventional and unconventiona…
Calorimetric evidence for two phase transitions in BaKFeAs with fermion pairing and quadrupling states
Ilya Shipulin, Nadia Stegani, Ilaria Maccari +9
Theoretically, materials that break multiple symmetries allow, under certain conditions, the formation of four-fermion condensates above the superconducting critical temperature. S…
Effects of high energy proton irradiation on the superconducting properties of Fe(Se,Te) thin films
Giulia Sylva, Emilio Bellingeri, Carlo Ferdeghini +11
In this paper we explore the effects of 3.5 MeV proton irradiation on Fe(Se,Te) thin films grown on CaF2. In particular, we carry out a systematic experimental investigation with d…
Experimental Evidences for Static Charge Density Waves in Iron Oxy-pnictides
A. Martinelli, P. Manfrinetti, A. Provino +5
In this Letter we report high-resolution synchrotron X-ray powder diffraction and transmission electron microscope analysis of Mn-substituted LaFeAsO samples, demonstrating that a…
Two-band conductivity of a FeSeTe film by reflectance measurements in the terahertz and infrared range
A. Perucchi, B. Joseph, S. Caramazza +7
We report an infrared spectroscopy study of a 200 nm thick FeSeTe film grown on LaAlO with T=13.7 K. We analyze the 20 K normal state absolute reflectance R…
Magneto Seebeck effect in REFeAsO (RE=rare earth) compounds: probing the magnon drag scenario
F. Caglieris, A. Braggio, I. Pallecchi +8
We investigate Seebeck effect in REFeAsO (RE=rare earth)compounds as a function of temperature and magnetic field up to 30T. The Seebeck curves are characterized by a broad negativ…
