Electron spin resonance ofGd3+andNd3+

Abstract: Low-temperature (1.6 KՇTՇ60 K) data of electron spin resonance for Gd 3ϩ and Nd 3ϩ diluted in LuInA 4 (AϭCu,Ni) compounds are presented. The results are interpreted in terms of a density of states at the Fermi level built up of a single s band for the Cu-based system and a multiple (s and d) bands for the Ni-based system. The susceptibility and specific heat data show negligible electron-electron exchange enhancement for both compounds. For the Cu-based system the exchange interaction between the rare-earth (G… Show more

“…These are reasonable assumptions because when “ dynamic ” effects are present the g -values are usually strongly T -dependent and when the bottleneck effect is relevant the Korringa rate b decreases with an increasing concentration of the magnetic ions21. Concerning the case of multiple band effects, one would expect the calculated g-shift to be much smaller than the measured one222324. As an example, we consider the pure EuFe 2 As 2 compound in the simplest scenario for the treatment of exchange interaction between Eu 2+ spins and conduction electron spins, i.e., b = ( π .…”

“…In the same temperature range, the negative ∆g ≈ -0.013 (2) indicates that the magnetic ions are interacting mainly with a small density of p-type conduction electron bands. [10][11][12].…”

“…That value is, in fact, very close to the one measured, b Ϸ 3.8͑4͒ Oe/ K. Therefore, we can conclude that the approximations made in Eqs. ͑1͒ and ͑2͒ are valid for this compound, and conduction electron-electron correlations, 15,16 q-dependent of the exchange interaction, J fs ͑q͒, 9 and multiple band effects 17 do not need to be taken into account in the analysis of our ESR data.…”
