Microstrain induced deviation from Néel's 1/d behaviour: Size-dependent magnetization in Bi1-xCaxFe1-yTiyO3-delta nanoparticles
Pavana S. V. Mocherla, M. B. Sahana, Ehab Abdelhamid +7
Magnetization of antiferromagnetic nanoparticles is known to generally scale up inversely to their diameter (d) according to Néel's model. Here we report a deviation from this conv…

Critical properties of the double exchange ferromagnet Nd0.4Pb0.4MnO3
M. Sahana, U. K. Roessler, Nilotpal Ghosh +6
Results of a study of dc-magnetization M(T, H), performed on a Nd0.6Pb0.4MnO3 single crystal in the temperature range around T_C (Curie temperature) which embraces the critical reg…
