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…
Relaxor ferromagnetic behavior below the antiferromagnetic transition in La0.5Ca0.5MnO3
R. Mahendiran, A. Maignan, C. Martin +2
A detailed reinvestigation of magnetization in La0.5Ca0.5MnO3 reveals that although a field of H = 7 T applied at T = 5 K after zero field cooling is insufficient to convert the lo…
Lattice coupled first order magnetoresistance transition in an A-type antiferromagnet: PrSrMnO
R. Mahendiran, C. Martin, A. Maignan +6
We investigated magnetic, magnetotransport and magnetostriction properties of the A-type antiferromagnet PrSrMnO which undergoes a first order paramagnetic-an…
Distinct origins of magnetic -field -induced resistivity irreversibility in two manganites with similar ground states : PrSrCaMnO and LaCaMnO
R. Mahendiran, A. Maignan, C. Martin +2
Our investigation of the magnetotransport in two charge ordered manganites with similar magnetic ground states reveals that the origin of magnetoresistance can not be concluded fro…
