TL;DR: In this article, it was shown that epitaxial film strain significantly modifies the properties of strontium ruthenates and exhibits a range of unusual emergent properties, such as electron nematic behavior and metamagnetism.
Abstract: $\mathrm{S}{\mathrm{r}}_{3}\mathrm{R}{\mathrm{u}}_{2}{\mathrm{O}}_{7}$ belongs to the family of layered strontium ruthenates and exhibits a range of unusual emergent properties, such as electron nematic behavior and metamagnetism. Here, we show that epitaxial film strain significantly modifies these phenomena. In particular, we observe enhanced magnetic interactions and an electron nematic phase that extends to much higher temperatures and over a larger magnetic-field range than in bulk single crystals. Furthermore, the films show an unusual anisotropic non-Fermi-liquid behavior that is controlled by the direction of the applied magnetic field. At high magnetic fields, the metamagnetic transition to a ferromagnetic phase recovers isotropic Fermi-liquid behavior. The results support the interpretation that these phenomena are linked to the special features of the Fermi surface, which can be tuned by both film strain and an applied magnetic field.

TL;DR: In this paper, a single-crystal compound with high-field magnetization up to 47 T and magnetic susceptibility measurements have been performed on a NdCu2Ge2 singlecrystal compounds.
Abstract: High-field magnetization up to 47 T and magnetic susceptibility measurements have been performed on a NdCu2Ge2 single-crystal compound. The susceptibility along the c-axis shows an antiferromagnetic behavior and an anomaly at T N =4.7 K . The magnetic easy direction is in the basal plane although moments are directed along the c-axis. The magnetization in the basal plane shows a knee around 6.6 T . The c-axis magnetization shows a metamagnetic transition at 2.3 T . The saturation magnetic moment estimated is 2.7 μ B . An analysis of the crystalline electric field has been made to discuss this magnetic behavior.

TL;DR: In this article, variations of magnetic properties in the UCoAl-UOsAl system on single and polycrystalline samples with different concentration of osmium were studied, and it was shown that Osmium can substitute Co in UCoA up to 20% while preserving ZrNiAl structure type.
