Antiferromagnetism in EuPdGe3

Strongly anisotropic and complex magnetic behavior in EuRhGe3

“…In contrast, the corresponding germanide EuPtGe 3 was found to possess a simple EM-AFM magnetic structure below T N ¼ 11 K, with the magnetic moments confined within the tetragonal ab plane [10]. Similarly, a sole AFM phase transition at T N ¼ 12.4 K to the state with the Eu magnetic moments lying within the ab plane was reported for EuPdGe 3 , but in this case rather an ICM character of the spin arrangement was anticipated [11,12]. In turn, the magnetic behavior in EuNiGe 3 was found fairly similar to that in EuPtSi 3 , namely an ICM-AFM order below T N ¼ 13.2 K is probably replaced at 10.5 K by a commensurate one with the Eu spins being nearly parallel to the c-axis [13,14].…”

Magnetism of the 35 K superconductor CsEuFe4As4

“…Clearly, the latter two contributions when added to the Fermi contact term must account for the measured H hf (0). For 151 Eu Mössbauer spectroscopy [29,30], as opposed to 57 Fe Mössbauer spectroscopy [31], there is no simple relation between the measured H hf (0) and the magnetic moment carried by Eu atoms. We note here that the calculated Eu magnetic moment of 6.7057 µ B is larger than the experimental moment of 5.9 µ B at 2 K determined from the magnetization measurements [4].…”

“…The fit of the H hf (T) data ((figure 17(a)) to equation (6) with J = S = 7/2 (corresponding to a free Eu 2+ ion) yields H hf (0) = 272.9(2.8) kOe and be explained by the fact that the measured hyperfine magn etic field at the 151 Eu nuclei is the sum of the Fermi contact term, the contribution from the valence and conduction band electrons, and the contribution due to the neighboring magn etic moments [30]. Clearly, the latter two contributions when added to the Fermi contact term must account for the measured H hf (0).…”

Magnetic properties of the noncentrosymmetric tetragonal antiferromagnet EuPtSi$_{3}$

“…A candidate for such behavior is EuPtSi 3 , belonging to a class of europium-based compounds crystallizing in the noncentrosymmetric tetragonal space group I4mm [19][20][21][22][23][24][25][26][27][28][29][30][31][32]. In a seminal study, Kumar and colleagues investigated single-crystal platelets grown from a tin solution [33].…”
