Magnetic order, metamagnetic transitions, and low-temperature spin freezing in Ca3Co2O6: an NMR study
G. Allodi, R. De Renzi, S. Agrestini +2
We report on a 59Co NMR investigation of the trigonal cobaltate Ca3Co2O6 carried out on a single crystal, providing precise determinations of the electric field gradient and chemic…
Nanoscopic coexistence of magnetic and superconducting states within the FeAs layers of CeFeAsO1-xFx
S. Sanna, R. De Renzi, T. Shiroka +8
We report on the coexistence of magnetic and superconducting states in CeFeAsO1-xFx for x=0.06(2), characterized by transition temperatures T_m=30 K and T_c=18 K, respectively. Zer…
Competing orders suppressed by disorder around a hidden quantum critical point in cuprate high Tc superconductors
S. Sanna, F. Coneri. A. Rigoldi, G. Concas +2
We report extensive muon spin rotation measurements on the lightly doped Y1-xCaxBa2Cu3O6+y compound, which allows us to disentangle the effect of disorder, controlled by random Ca2…
