We report an interesting correlation among the electroresistance, extrinsic magnetoresistance, and threshold current (I_th) - beyond which a regime of negative differential resistance sets in - via...
Ferromagnetism in nanoscale BiFeO3 (2007)
Mazumder, R., Devi, P. Sujatha, Bhattacharya, Dipten, Choudhury, P., Sen, A., Raja, M.
A remarkably high saturation magnetization of ~0.4mu_B/Fe along with room temperature ferromagnetic hysteresis loop has been observed in nanoscale (4-40 nm) multiferroic BiFeO_3 which in bulk form...

The nature of orbital order-disorder transition has been studied in the La(1-x)Nd(x)MnO(3) (x = 0.0-1.0) series which covers the entire range between two end points - LaMnO(3) and NdMnO(3) - as well...
Preparation, Structure and Electrical Properties of the System LaCr(1-x)Ti(x)O3. (1998)
Devi, P. Sujatha, Rao, M. Subba
Ceramic lanthanum chromite has been emphasized by many workers as the most promising candidate material for high-temperature technology. Attempts have been made to prepare highly dense and...
