Neutron scattering evidence for magnetic field driven abrupt magnetic and structural transitions in a phase separated manganite
C. Yaicle, C. Martin, Z. Jirak +12
Substitutions at the Mn-site of the charge-ordered Pr0.5Ca0.5MnO3 manganite is an effective way to induce abrupt jumps on the magnetic field driven magnetization curve. In order to…
Field-Induced Magnetization Steps in Intermetallic Compounds and Manganese Oxides: The Martensitic Scenario
V. Hardy, S. Majumdar, S. Crowe +9
Field-induced magnetization jumps with similar characteristics are observed at low temperature for the intermetallic germanide Gd5Ge4and the mixed-valent manganite Pr0.6Ca0.4Mn0.96…
Staircase-like metamagnetic transitions in phase-separated manganites: influence of thermal and mechanical treatments
V. Hardy, C. Yaicle, S. Hebert +4
Substitutions in the Mn-sublattice of antiferromagnetic, charge and orbitally ordered manganites was recently found to produce intriguing metamagnetic transitions, consisting of a…
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…
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…
