Induced Ferromagnetism and Colossal Magnetoresistance by Ir-Doping in Pr1-xCaxMnO3
Sylvie Hebert, Antoine Maignan, Raymond Fresard +4
The doping of the manganese site by iridium (up to 15%) in the small A cation manganites Pr_{1-x}Ca_xMnO_3 (0.4 < x < 0.8), has been investigated as a new method to suppress charge…
Large Thermopower in Metallic Oxides: Misfit Cobaltites and Mangano-Ruthenates
Sylvie Hebert, Christine Martin, Antoine Maignan +3
Two different kinds of metal transition oxides have been studied for their large thermopower values. The first one corresponds to the Tl-based misfit cobaltite which is a hole-dope…
Giant anisotropic magnetostriction in PrSrMnO
R. Mahendiran, C. Marquina, M. R. Ibarra +4
Magnetic, linear thermal expansion (LTE), anisotropic () and volume () magnetostriction properties of PrSrMnO were investigated. The LTE decreases smoot…
Lattice coupled first order magnetoresistance transition in an A-type antiferromagnet: PrSrMnO
R. Mahendiran, C. Martin, A. Maignan +6
We investigated magnetic, magnetotransport and magnetostriction properties of the A-type antiferromagnet PrSrMnO which undergoes a first order paramagnetic-an…
Distinct origins of magnetic -field -induced resistivity irreversibility in two manganites with similar ground states : PrSrCaMnO and LaCaMnO
R. Mahendiran, A. Maignan, C. Martin +2
Our investigation of the magnetotransport in two charge ordered manganites with similar magnetic ground states reveals that the origin of magnetoresistance can not be concluded fro…
Magnetic-field -induced structural changes in the electron doped manganites: CaxSm1-xMnO3 (x = 0.8, 0.85)
R. Mahendiran, P. A. Algarabel, L. Morellon +7
We studied the correlation between magnetic, electrical, structural, and magnetostriction properties of the electron doped manganites CaSmMnO (x = 0.85, 0.8). The p…
Rhodium Doped Manganites : Ferromagnetism and Metallicity
Bernard Raveau, Sylvie Hebert, Antoine Maignan +3
The possibility to induce ferromagnetism and insulator to metal transitions in small A site cation manganites Ln_{1-x}Ca_xMnO_3 by rhodium doping is shown for the first time. Colos…
Instability of metal-insulator transition against thermal cycling in phase separated Cr-doped manganites
R. Mahendiran, B. Raveau, M. Hervieu +2
We show that metal-insulator transition in Pr0.5Ca0.5Mn1-xCrxO3 (x = 0.015-0.025) is unstable against thermal cycling. Insulator-metal transition shifts down and low temperature re…
