In divalent Eu systems, the 4f local moment has a pure spin state J = S = 7/2. Although the absence of orbital moment precludes crystal electric field effects, we report a sizable magnetic anisotropy in single crystals of EuRh2Si2. We observed a surprisingly complex magnetic behavior with three successive phase transitions. The Eu(2+) moments order in a probably amplitude-modulated structure below 24.5 K, undergoing a further transition to a structure that is possibly of the equal-moment type…

Charge, lattice and magnetism across the valence crossover in EuIr2Si2 single crystals.
TLDR
It is shown that the intermediate/fluctuating valence duality is to some extent represented in the interconfiguration fluctuation model commonly used to analyze data on valence-fluctuated systems, and this model cannot describe the different physical properties of [Formula] with a single set of parameters.
Crystal Structure and Magnetism of Noncentrosymmetric Eu2Pd2Sn
TLDR
The new intermetallic compound Eu2Pd2Sn has been investigated, revealing that this compound possesses the noncentrosymmetric Ca2 Pd2Ge structure type being, so far, the only rare-earth-based representative.

TLDR
A detailed study of the evolution of the magnetic order in this model system from a FM state with moments along the very hard c direction towards the yet unknown magnetic state at x=0.27 is presented.
Spin Orientation of Two-Dimensional Electrons Driven by Temperature-Tunable Competition of Spin-Orbit and Exchange-Magnetic Interactions.
TLDR
The findings show that the direction of the spins and the spin-splitting of the two-dimensional electrons at the surface can be manipulated in a controlled way by using only one parameter: the temperature.
Divalent EuRh2Si2 as a reference for the Luttinger theorem and antiferromagnetism in trivalent heavy-fermion YbRh2Si2
TLDR
By studying divalent EuRh 2Si2, the authors gain insight into the electronic states of the trivalent heavy fermion system YbRh2Si2 and show that it experimentally demonstrates Luttinger’s theorem.
