A Novel Magnetic Material by Design: Observation of Yb(3+) with Spin-1/2 in Yb(x)Pt(5)P
[Image: see text] The localized f-electrons enrich the magnetic properties in rare-earth-based intermetallics. Among those, compounds with heavier 4d and 5d transition metals are even more fascinating because anomalous electronic properties may be induced by the hybridization of 4f and itinerant con...

description | [Image: see text] The localized f-electrons enrich the magnetic properties in rare-earth-based intermetallics. Among those, compounds with heavier 4d and 5d transition metals are even more fascinating because anomalous electronic properties may be induced by the hybridization of 4f and itinerant conduction electrons primarily from the d orbitals. Here, we describe the observation of trivalent Yb(3+) with S = 1/2 at low temperatures in Yb(x)Pt(5)P, the first of a new family of materials. Yb(x)Pt(5)P (0.23 ≤ x ≤ 0.96) phases were synthesized and structurally characterized. They exhibit a large homogeneity width with the Yb ratio exclusively occupying the 1a site in the anti-CeCoIn(5) structure. Moreover, a sudden resistivity drop could be found in Yb(x)Pt(5)P below ∼0.6 K, which requires further investigation. First-principles electronic structure calculations substantiate the antiferromagnetic ground state and indicate that two-dimensional nesting around the Fermi level may give rise to exotic physical properties, such as superconductivity. Yb(x)Pt(5)P appears to be a unique case among materials. |
