Grüneisen rule in cubic rare-earth cage systems : the examples of LaB and LaPtGe
Mehdi Amara, Christine Opagiste, Natalya Yu. Shitsevalova
In some intermetallic compounds, the crystallographic structure allows for an unusual latitude of movement of lanthanide ions inside so-called cages. Examples of such magnetic cage…
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…
Dynamical splitting of cubic crystal field levels in rare-earth cage compounds
Mehdi Amara
The Crystalline Electric Field (CEF) influence is usually described by considering an ideally symmetrical rare-earth site. In the case of cage compounds, ample excursions of the ra…
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…
The centrifugal Jahn-Teller effect in rare-earth cage systems
Mehdi Amara
The analysis of the properties of rare-earth based materials relies on the Crystalline Electric Field theory. This theory has to be reconsidered in case of cage-type compounds, whe…
