Upper critical field and fluctuation conductivity in the critical regime of doped SmFeAsO
I. Pallecchi, C. Fanciulli, M. Tropeano +7
We measure magnetotransport of F doped SmFeAsO samples up to 28T and we extract the upper critical fields, using different criteria. In order to circumvent the problem of criterion…
Magnetic properties of undoped and 15%F doped SmFeAsO compounds
R. Cimberle, C. Ferdeghini, F. Canepa +5
In this paper the magnetic behaviour of SmFeAsO and SmFeAs(O0.85F0.15) samples is presented and discussed. Molar susceptibility of SmFeAsO exhibits a local peak at T around 140K du…
Crystal and magnetic structure of (La0.70Ca0.30)(CryMn1-y)O3: a neutron powder diffraction study
L. Capogna, A. Martinelli, M. G. Francesconi +7
The crystal and magnetic structure of (La0.70Ca0.30)(CryMn1-y)O3 for y = 0.70, 0.50 and 0.15 has been investigated using neutron powder diffraction. The three samples crystallize i…
Synthesis effects on the magnetic and superconducting properties of RuSr2GdCu2O8
R. Masini, C. Artini, M. R. Cimberle +3
A systematic study on the synthesis of the Ru-1212 compound by preparing a series of samples that were annealed at increasing temperatures and then quenched has been performed. It…
Anelastic relaxation process of polaronic origin in La{2-x}Sr{x}CuO{4}: interaction between the charge stripes and pinning centers
F. Cordero, A. Paolone, R. Cantelli +1
The evolution of an anelastic relaxation process occurring around 80 K in La{2-x}Sr{x}CuO{4} at a measuring frequency of ~1 kHz has been followed from x = 0.0075 to the overdoped r…
Anelastic spectroscopy study of the spin-glass and cluster spin-glass phases of LaSrCuO
A. Paolone, F. Cordero, R. Cantelli +1
The anelastic spectra of LaSrCuO have been measured at liquid He temperatures slightly below and above the concentration which is considere…
Acoustic measurement of the low-energy excitations in Nd2-xCexCuO4
F. Cordero, C. R. Grandini, M. Ferretti
The complex dynamic Young's modulus of ceramic Nd2-xCexCuO4 with x = 0, 0.05 and 0.20 has been measured from 1.5 to 100 K at frequencies of 1-10 kHz. In the undoped sample the modu…
Synthesis and characterization of superconducting RuSr2GdCu2O8
C. Artini, M. M. Carnasciali, G. A. Costa +4
We report on structural, electrical and magnetic properties of RuSr2GdCu2O8 samples made by systematic synthesis work so that they differ from one onether in number of annealings a…
Glassy dynamics of the inhomogeneous metallic phase in La1-xCaxMnO3
F. Cordero, C. Castellano, R. Cantelli +1
The anelastic spectra (elastic energy loss and dynamic modulus versus temperature) of La1-xCaxMnO3 have been measured for 0.33< x < 0.5. A peak in the imaginary part of the elastic…
Pinning of the domain walls of the cluster spin-glass phase in LTT La_{2-x}Ba_xCuO_4
F. Cordero, A. Paolone, R. Cantelli +1
We compare the low frequency (~1 kHz) anelastic spectra of La_{2-x}Sr_xCuO_4 and La_{2-x}Ba_xCuO_4 at x = 0.03 and 0.06 in the temperature region where the freezing into the cluste…
Observation of the cluster spin-glass phase in La_{2-x}Sr_{x}CuO_{4} by anelastic spectroscopy

An increase of the acoustic absorption is found in La_{2-x}Sr_{x}CuO_{4} (x = 0.019, 0.03 and 0.06) close to the temperatures at which freezing of the spin fluctuations in antiferr…
Tunneling driven tilt modes of the O octahedra in La{2-x}Sr{x}CuO{4}: strong dependence on doping
