Giant magnetothermopower in charge ordered Nd0.75Na0.25MnO3
D. V. Maheswar Repaka, R. Mahendiran
We report magnetization, resistivity and thermopower in the charge-orbital ordered antiferromagnet Nd0.75Na0.25MnO3. Magnetic-field induced collapse of antiferromagnetism is found…
Magnetothermal cooling with a phase separated manganite
A. Rebello, R. Mahendiran
We show that temperature of a current (I = 20 mA) carrying manganite (Nd0.5Ca0.5Mn0.93Ni0.07O3) in presence of a magnetic field (H) decreases abruptly as much as deltaT = 45 K (7 K…
Electrical, magnetic, magnetodielectric and magnetoabsorption studies in multiferroic GaFeO3
V. B. Naik, R. Mahendiran
We report electrical, magnetic, magnetodielectric and magnetoabsorption properties of a polycrystalline GaFeO3. The resistivity measurement shows that the sample is highly insulati…
Huge ac magnetoresistance in La0.7Sr0.3MnO3 in sub- kilo gauss magnetic fields
A. Rebello, V. B. Naik, R. Mahendiran
We report dynamical magnetotransport in a ferromagnetic metallic oxide, La0.7Sr0.3MnO3 using the ac impedance technique. The temperature dependence of the ac resistance(R) and the…
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…
Ca0.85Sm0.15MnO3: A mixed antiferromagnet with unusual properties
R. Mahendiran, A. Maignan, C. Martin +2
We investigated electrical and magnetic properties of the electron-doped manganites Ca1-xSmxMnO3 (0<x<0.2). Our results indicate the possibility of phase separation in electron dop…
