Magnetic states and spin-glass properties in Bi0.67Ca0.33MnO3: macroscopic ac measurements and neutron scattering
M. Giot, A. Pautrat, G. Andre +3
We report on the magnetic properties of the manganite Bi_{1-x}Ca_{x}MnO_3 (x=0.33) at low temperature. The analysis of the field expansion of the ac susceptibility and the observat…
Small angle neutron scattering study of the step-like magnetic transformation in Pr0.70Ca0.30MnO3
D. Saurel, Ch. Simon, A. Brulet +2
Small angle neutron scattering (SANS) magnetic and electrical transport measurements were performed to study a single crystal of Pr0.7Ca0.3MnO3, a colossal magnetoresistive (CMR) m…
Magnetic field dependence of the magnetic phase separation in Pr1-xCaxMnO3 manganites studied by small-angle neutron scattering
Damien Saurel, Annie Brulet, Andre Heinemann +3
Transport properties of manganese oxides suggest that their colossal magnetoresistance (CMR) is due to percolation between ferromagnetic metallic (FM) clusters in an antiferromagne…
Non-linear effects and Joule heating in I-V curves in manganites
Silvana Mercone, Raymond Fresard, Vincent Caignaert +6
We study the influence of the Joule effect on the non-linear behavior of the transport I-V curves in polycrystalline samples of the manganite Pr0.8Ca0.2MnO3 by using the crystallin…
Tailoring of ferromagnetic Pr0.85Ca0.15MnO3/ferroelectric Ba0.6Sr0.4TiO3 superlattices for multiferroic properties
P. Murugavel, D. Saurel, W. Prellier +2
Superlattices composed of ferromagnetic Pr0.85Ca0.15MnO3 and ferroelectric Ba0.6Sr0.4TiO3 layers were fabricated on (100) SrTiO3 substrates by a pulsed-laser deposition method. The…
Neutron scattering evidence for magnetic field driven abrupt magnetic and structural transitions in a phase separated manganite
C. Yaicle, C. Martin, Z. Jirak +12
Substitutions at the Mn-site of the charge-ordered Pr0.5Ca0.5MnO3 manganite is an effective way to induce abrupt jumps on the magnetic field driven magnetization curve. In order to…
