Spin excitations in the antiferromagnet NaNiO2
Sophie De Brion, C. Darie, M. Hopzapfel +5
In NaNiO2, Ni3+ ions form a quasi two dimensional triangular lattice of S = 1=2 spins. The magnetic order observed below 20K has been described as an A type antiferromagnet with fe…
Decoupling of orbital and spin degrees of freedom in Li1-xNaxNiO2
M. Hopzapfel, S. Debrion, C. Darie +6
In the Li1-xNaxNiO2 solid solutions three different single phase regions exist: for x > 0.9, forx = 0.7 and for x < 0.3. Although the intermediate compound does not show the cooper…
Phase separation effects in charge-ordered Pr0.5Ca0.5MnO3 thin film
S. de Brion, G. Storch, G. Chouteau +3
Compressed Pr0.5Ca0.5MnO3 films (250nm) deposited on LaAlO3 have been studied by Electron Spin Resonance technique under high frequency and high magnetic field. We show evidences f…
Interlayer Magnetic Frustration in Quasi-stoichiometric Li1-xNi1+xO2
E. Chappel, M. D. Nunez-Regueiro, S. de Brion +4
Susceptibility, high-field magnetization and submillimeter wave electron spin resonance measurements of layered quasi-stoichiometric Li1-xNi1+xO2 are reported and compared to isomo…
Influence of Nd on the magnetic properties of Nd1-xCaxMnO3
F. Dupont, F. Millange, S. de Brion +2
The role played by the Nd ions in the magnetic properties of Nd0.5Ca0.5MnO3 and Nd0.7Ca0.3MnO3 is studied using static magnetization, neutron diffraction and high frequency (9.4-47…
Charge, Orbital and Magnetic Order in Nd0.5Ca0.5MnO3
F. millange, S. de Brion, G. Chouteau
In the manganite Nd0.5Ca0.5MnO3, charge ordering occurs at much higher temperature than the antiferromagnetic order (TCO=250K,TN=160K). The magnetic behavior of the phase TN<T<TCO…
