Inverse magnetocaloric effect in ferromagnetic Sm0.6-xLaxSr0.4MnO3 due to 4f-3d exchange interaction
V. B. Naik, R. Mahendiran
We report magnetic and magnetocaloric properties of Sm0.6-xLaxSr0.4MnO3 (x = 0-0.6). A rapid increase around TC and an anomalous peak at a temperature T*<<TC occur in magnetization…
A large magnetoinductance effect in La0.67Ba0.33MnO3
V. B. Naik, A. Rebello, R. Mahendiran
We report four probe impedance of La0.67Ba0.33MnO3 at f = 100 kHz under different dc bias magnetic fields. The ac resistance (R) exhibits a peak around Tp = 325 K which is accompan…
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…
Magnetic and magnetoelectric studies in pure and cation doped BiFeO3
V. B. Naik, R. Mahendiran
We report magnetic and magnetoelectric studies on BiFeO3 and divalent cation (A) suvtitute Bi0.7A0.3FeO3 (A = Sr,Ba, and Sr0.5Ba0.5). It is shown that the rapid increase of magneti…
Magnetically tunable rf wave absorption in polycrystalline La0.67Ba0.33MnO3
V. B. Naik, R. Mahendiran
We investigated temperature and magnetic field dependent radio-frequency electromagnetic absorption in La0.67Ba0.33MnO3 by monitoring changes in resonance frequency (fr) and curren…
