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…
Stress deformations and structural quenching in Sm0.5Ca0.5MnO3 thin films allow a huge decrease of the charge order melting magnetic field
E. Rauwel, W. Prellier, B. Mercey +2
Thin films of Sm0.5Ca0.5MnO3 manganites with charge ordering (CO) properties and colossal magnetoresistance were synthesized by pulsed laser deposition technique on (100)-SrTiO3 an…
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…
High magnetic field transport measurement of charge-ordered PrCaMnO strained thin films
W. Prellier, E. Rauwel Buzin, S. de Brion +3
We have investigated the magnetic-field-induced phase transition of charge-ordered (CO) PrCaMnO thin films, deposited onto (100)-oriented LaAlO and (100)-or…
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…
