Abstract

Two remarkable pentanuclear 3d–4f clusters of Ln₃Fe₂ were synthesized and structurally characterized. Magnetic studies indicate that Gd₃Fe₂ possesses the significant magnetic entropy change (−ΔS_m) of 31.7 J kg⁻¹ K⁻¹ and slow magnetic relaxation is observed in the anisotropic Dy-analogue.
