Magnetism of fine particles of Kondo lattices, obtained by high-energy ball-milling
The study of WL flares have been rendered very difficult by their short duration and very low contrast which makes their observations from Earth rare and of poor quality.

Steric eÿects have recently been investigated by doping the A-type antiferromagnets EuMnO3 and GdMnO3 with smaller Y cations at the rare earth site.
Multiferroic properties and magnetic structure of Sm1-xYxMnO3
In contrast to TbMnO3 , however, there is no evidence in our data to suggest that the rare earth magnetism in Sm1−xYxMnO3 plays a role in influencing the magnetic ordering of the Mn3+ moments.

In this context, solid state materials such as rare-earth ion doped crystals (REIC) offer a prime alternative to atomic vapors since they combine the absence of motion with long coherence lifetime and large inhomogeneous width.
Revival of Silenced Echo and Quantum Memory for Light
Our results highlight the potential of rare-earth-ions doped crystals for entangled quantum nodes and bring quantum networks based on solid-state resources one step closer.
Heralded quantum entanglement between two crystals
In this context, important results have already been obtained with rare-earth-ion (RE) doped crystals used as quantum memories.

The deformation properties display an identical behaviour for all the nuclear chains. A good description of the above deformation transitions in the RMF theory in all the isotopic chains leads to a successful reproduction of the anomalous behaviour of the empirical isotopic shifts of the rare-earth nuclei.
