“…It is comparable to those reported for other metallic spin glass systems [13][14][15][16][17]. To investigate the nature of the spin-glass state more deeply, the well-known Vögel-Fulcher law [18] was applied to the data as follows:…”

The magnetic and thermal properties of Ce 1−x Er x Al 2 compounds have been studied using electrical resistivity and magnetic susceptibility measurements. The magnetic ordering temperature continuously changes with a change from antiferro-magnetism (CeAl 2 ) to ferro-magnetism (ErAl 2 ) appears. The magnetic ordering temperature is continuously changed as a function of Er concentration x. A spin glass behavior was found between x= 0.08 and 0.4. The magnetic phase diagram was compiled as a function of x.

“…16 Antiferromagnetic coupling [17][18][19] lends itself more readily to geometric frustration than ferromagnetic coupling, explaining the limited number of metallic, ferromagnetically coupled cluster-glass systems. Several cases are known, where a cluster-glass state arises from a ferromagnetic ground state in metal oxides, [20][21][22][23] 26,27 dynamic fluctuations of crystalfield levels have been suggested as the underlying mechanism for the magnetic frustration in PrRhSn 3 , 28 based on the fact that neither site disorder nor geometric frustration is present in this compound.…”

In the presented work, Sc 3.1 In, a weak itinerant ferromagnet with no magnetic constituents, is doped with Er 3+ local moment ions, to form (Sc 1−x Er x ) 3.1 In. As x increases, the Weiss-like temperature θ stays positive and nearly triples up to x = 0.10. Moreover, Er doping of as little as x = 0.02 induces a cluster-glass state, which persists up to x = 0.10, as evidenced by dc and ac susceptibility measurements, and confirmed by the Vogel-Fulcher analysis.

“…Or is it the result of the combined influence of strong electronic correlations and disorder-induced localization, which ought to be treated in the framework of Anderson vs. Mott-Hubbard localization [14,15]. In order to address such issues we have performed a detailed study of the electronic transport properties of a U heavy fermion compound with moderate and known disorder, namely URh 2 Ge 2 [16].…”

We present a detailed study of the electronic transport properties on a single crystalline specimen of the moderately disordered heavy fermion system URh2Ge2. For this material, we find glassy electronic transport in a single crystalline compound. We derive the temperature dependence of the electrical conductivity and establish metallicity by means of optical conductivity and Hall effect measurements. The overall behavior of the electronic transport properties closely resembles that of metallic glasses, with at low temperatures an additional minor spin disorder contribution. We argue that this glassy electronic behavior in a crystalline compound reflects the enhancement of disorder effects as consequence of strong electronic correlations.
