Element selective magnetism in Ho0.5Nd0.5Fe3(<

Structural, magnetic, electronic, and dilatation properties of the ordered solid solutions Ln0.2Sr0.8CoO3-δ (Ln = Sm, Gd, Dy) with the same oxygen nonstoichiometry index δ

“…These values are significantly lower than the expected contributions from non-interacting rare earth elements (0.2 х µ eff (Re 3+ )), being equal to 0.17, 1.56, and 2.13µ B for Sm 3+ , Gd 3+ и Dy 3+ respectively. The given difference suggests a magnetic interaction between the sublattices of the rare-earth element and cobalt, similar to the observed magnetic coupling in the Ho 0.5 Nd 0.5 Fe 3 (BO 3 ) 4 compounds between the Nd 3+ , Ho 3+ and Fe 3+ ions [31]. Temperature dependences of the inverse magnetic susceptibility of the samples under study are shown in Fig.…”

Hard X-ray magnetochiral dichroism in a paramagnetic molecular 4f complex

“…Such quadrupolar 2p-4f transitions are easily distinguishable either in X-ray MCD (XMCD) or in resonant inelastic X-ray scattering spectra at the L 3 -edge 64,65 of rare-earths, whereas their contribution at the L 2 -edge is more difficult to disentangle. 66 We used le (L) or right (R) circularly polarised X-rays whose wave vector, k, was parallel (+) or antiparallel (À) to the external magnetic eld, B. To identify two enantiomeric single crystals of 1 each displaying an optimal response, X-ray NCD (XNCD) spectra were recorded at room temperature on several crystals already characterised by X-ray crystallography, as crystals of macroscopically similar appearance do not yield the same XNCD intensity (Fig.…”

A cookbook for the investigation of coordination polymers by transition metal K-edge XMCD

“…As for temperature, the effect related to the different values of the magnetic field described here is purely related to the measurements conditions, since all the measurements are performed below the Curie temperature and so in the same magnetic ordering state. Nevertheless, it is interesting to point out that XMCD measurements at different magnetic field can also bring valuable information on the investigated compound (Train et al, 2004;Bartolome ´et al, 2005;Osawa et al, 2007;Boada et al, 2010b;Chaboy et al, 2010;Guglieri et al, 2012;Koumousi, 2015;Jafri, 2016;Lahiri et al, 2016;Platunov et al, 2019;Pajerowski et al, 2020). Finally, our goal here was to optimize the value of the applied magnetic field for our PBAs but not to perform element-selective magnetic hysteresis from XMCD; these measurements require either the direction of the magnetic field to be fixed and the helicity of the photons switched (Pizzini et al, 1997), or to apply an appropriate procedure if the helicity cannot be switched.…”
