Cage multipoles in rare-earth hexaborides
Mehdi Amara, Rose-Marie Galera
In rare-earth cage compounds, the guest 4f ion cannot be considered as fixed at the centre of its cage. As result of the electronic degeneracy of the 4f shell, single-ion or collec…
Retrieving CeB's lost magnetic entropy
Mehdi Amara, Christine Opagiste, Rose-Marie Galera
The reported temperature variations of CeB6 s magnetic entropy are inconsistent with the fourfold degeneracy of the crystal field ground state. This old question is here addressed…
Crystal field investigation in the light rare earth RPtSi compounds
R. M. Galéra, C. Opagiste, M. Amara +3
The crystalline electric field (CEF) is investigated in PrPtSi and NdPtSi by neutron spectroscopy (NS). At low temperature, the number of observ…
CeB6 macroscopically revisited
M. Amara, R. -M. Galéra
Magnetic susceptibility anisotropy and high sensitivity magnetostriction measurements are used to investigate the symmetry of CeB6 ordered states. The antiferromagnetic state is co…
Crystal growth, structure and ferromagnetic properties of a Ce3Pt23Si11 single crystal
C. Opagiste, C. Paulsen, E. Lhotel +4
A high-quality single crystal of Ce3Pt23Si11 has been grown using the Czochralski method. The crystal structure is presented and the chemical composition has been checked using an…
Magnetic properties of HO2 thin films
Nicolas Hadacek, Alexandre Nossov, Laurent Ranno +2
We report on the magnetic and transport studies of hafnium oxide thin films grown by pulsed-laser deposition on sapphire substrates under different oxygen pressures, ranging from 1…
