Magnetic structure driven by monoclinic distortions in the double perovskite Sr2YRuO6
P. L. Bernardo, L. Ghivelder, H. S. Amorim +2
The monoclinic double-perovskite Sr2YRuO6 has recently gained a renewed interest in order to get a deeper insight into the exotic magnetic ground states associated with geometric f…
Two dimensional frustrated magnetic state in superconducting RuSr2Eu1.5Ce0.5Cu2O10 (Ru-1222)
S. Garcia, L. Ghivelder, I. Felner
In this paper we investigate the magnetic state and the role of the crystalline structure in RuSr2Eu1.5Ce0.5Cu2O10 (Ru-1222). Measurements were made in the isomorphic series (Nb1-x…

M. G. das Virgens, S. García, L. Ghivelder
The lower critical field of the grains, , and the intragrain critical current density, , were determined for the superconducting ruthenate-cuprate RuSrGd$_{1.5…
Intergranular pinning potential and critical current in the magnetic superconductor RuSr2Gd1.5Ce0.5Cu2O10
M. G. das Virgens, S. Garcia, M. A. Continentino +1
The intergranular pinning potential U and the critical current density Jc for polycrystalline RuSr2Gd1.5Ce0.5Cu2O10 ruthenate-cuprate were determined at zero magnetic field and tem…
I-V curves and intergranular flux creep activation energy in the magnetic superconductor RuSr2GdCu2O8
S. Garcia, L. Ghivelder
A systematic study of I-V characteristic curves for RuSr2GdCu2O8 [Ru-(1212)] is presented, with magnetic fields up to 3 T and 5 K<T<30 K, in the region of the superconducting trans…
Magneto-transport study of intra- and intergrain transitions in the magnetic superconductors RuSr2GdCu2O8 and RuSr2(Gd1.5Ce0.5)Cu2O10
S. Garcia, J. E. Musa, R. S. Freitas +1
A characterization of the magnetic superconductors RuSr2GdCu2O8 [Ru-(1212)] and RuSr2(Gd1.5Ce0.5)Cu2O10 [Ru-(1222)] through resistance measurements as a function of temperature and…
