Abstract

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.
