Transient quantum isolation and critical behavior in the magnetization dynamics of half-metallic manganites
Tommaso Pincelli, Riccardo Cucini, Adriano Verna +22
We combine time resolved pump-probe Magneto-Optical Kerr Effect and Photoelectron Spectroscopy experiments supported by theoretical analysis to determine the relaxation dynamics of…
Charge and nematic orders in AFeAs (A= Rb,Cs) superconductors
M. Moroni, G. Prando, S. Aswartham +5
We discuss the results of As Nuclear Quadrupole Resonance (NQR) and muon spin relaxation measurements in AFeAs (A= Cs, Rb) iron-based superconductors. We demonstrate…
Dispersive charge density wave excitations and temperature dependent commensuration in Bi2Sr2CaCu2O8+δ
Laura Chaix, Giacomo Ghiringhelli, Yingying Peng +14
Experimental evidence on high-Tc cuprates reveals ubiquitous charge density wave (CDW) modulations, which coexist with superconductivity. Although the CDW had been predicted by the…
Photoresponse dynamics in amorphous-LaAlO/SrTiO interfaces
Emiliano Di Gennaro, Ubaldo Coscia, Giuseppina Ambrosone +3
The time-resolved photoconductance of amorphous and crystalline LaAlO/SrTiO interfaces, both hosting an interfacial 2-dimensional electron gas, is investigated under irradi…
Amorphous ferromagnetism and re-entrant magnetic glassiness in SmMoO: new insights into the electronic phase diagram of pyrochlore molybdates
G. Prando, P. Carretta, A. U. B. Wolter +3
We discuss the magnetic properties of a SmMoO single crystal as investigated by means of different experimental techniques. In the literature, a conventional itin…
Effect of external pressure on the magnetic properties of CoAsO ( = La, Pr, Sm): a SR study
G. Prando, S. Sanna, R. Khasanov +6
We report on a detailed investigation of the itinerant ferromagnets LaCoAsO, PrCoAsO and SmCoAsO performed by means of muon spin spectroscopy upon the application of external hydro…
