Large positive magnetocaloric effect in a perovskite manganite
R. Mahendiran, B. G. Ueland, P. Schiffer +6
We investigate the magnetothermodynamic properties of the perovskite manganite Pr0.46Sr0.54MnO3. Our data imply that the paramagnetic to antiferromagnetic transition at TN = 210 K…

Giant frequency dependence of dynamic freezing in nanocrystalline ferromagnetic LaCo0.5Mn0.5O3
R. Mahendiran, Y. Breard, M. Hervieu +2
We have investigated the magnetic properties of nanocrystalline LaCo0.5Mn0.5O3. The temperature dependence of the imaginary part of the a.c. susceptibility shows a strongly frequen…
