Staircase effect in metamagnetic transitions of charge and orbitally ordered manganites
V. Hardy, S. Hebert, A. Maignan +3
This paper reports on peculiar metamagnetic transitions which take place in antiferromagnetic, charge and orbitally ordered (AFCOO) manganites. At very low temperatures, the virgin…
Transport and magnetic properties in YBaCo2O5.45: Focus on the high-temperature transition
A. Pautrat, P. Boullay, S. Hebert +1
The electronic transport properties and the magnetic susceptibility were measured in detail in . Close to the so-called metal-insulator transition, strong effects…
Dome-shaped magnetic phase diagram of thermoelectric layered cobaltites
J. Sugiyama, J. H. Brewer, E. J. Ansaldo +7
Using muon spin spectroscopy we have found that, for both NaCoO (0.6 0.9) and 3- and 4-layer cobaltites, a common low temperature magnetic state (which in som…
Ultra-sharp magnetization steps in perovskite manganites
R. Mahendiran, A. Maignan, S. Hebert +5
We report a detailed study of step-like metamagnetic transitions in the magnetization and resistivity of polycrystalline Pr0.5Ca0.5Mn0.95Co0.05O3. The steps have a sudden onset bel…
Quantum Tunneling of the Magnetization in the Ising Chain Compound Ca3Co2O6
A. Maignan, V. Hardy, S. Hebert +5
The magnetic behavior of the Ca3Co2O6 spin chain compound is characterized by a large Ising-like character of its ferromagnetic chains, set on triangular lattice, that are antiferr…
Magnetic field dependent specific heat and enhanced Wilson ratio in strongly correlated layered cobalt oxide
P. Limelette, H. Muguerra, S. Hebert
We have investigated the low temperature specific heat properties as a function of magnetic field in the strongly correlated layered cobalt oxide [BiBaKO]CoO$…
