The use of non-cash payment schemes is particularly widespread in France where the number of non-cash transactions is in fact well above the European average. Though they have different features corresponding to users’ varying needs (payments may be face-to-face, remote or recurring, for...

The dielectric permittivity and resistivity have been measured simultaneously as a function of magnetic field in Pr<Subscript>1-x</Subscript>Ca<Subscript>x</Subscript>MnO<Subscript>3</Sub script> crystals with different doping. A huge increase of dielectric permittivity was detected near percolation threshold. The dielectric and conductive properties are found to...<//sub></subscript></subscript></subscript>

The magnetic properties of a polycrystalline Sr<Subscript>3</Subscript>NiIrO<Subscript>6</Subscript> sample have been investigated by means of susceptibility and magnetization measurements. On the one hand, it is found that this compound, made of magnetic chains on a triangular lattice, behaves very similarly to Ca<Subscript>3</Subscript>CoRhO<Subscript>6</Subscript> and Ca<Subscript>3</Subscript>CoIrO<Subscript>6</Subscript>.

We report on the resistivity (ρ), thermoelectric power (S for Seebeck) and magnetic measurements of the series Pr<Subscript>1-x</Subscript>Ca<Subscript>x</Subscript>CrO<Subscript>3</Sub script> (x=0.0–0.5). These orthochromites exhibit a T independent, large and positive S, from 100 K to 700 K which follows the Cr<Superscript>4+</Superscript> concentration.

The crystal and magnetic structures of Pr<Subscript>0.15</Subscript>Sr<Subscript>0.85</Subscript>MnO<Subscript>3< /Subscript> manganite have been studied by means of powder X-ray and neutron diffraction in the temperature range 10–400 K at high external pressures up to 55 and 4 GPa, respectively.
