Abstract

The temperature dependence of magnetic susceptibility, χ, of a cubic Laves phase compound ScCo 2 was measured in the temperature range 4.2–1018 K and found to have a broad maximum at about 600 K. The temperature dependent Knight shift, K , of Sc was obtained from NMR experiment below room temperature. The K vs χ plot gives a straight line resulting in -41 kOe/ µ B as a transferred hyperfine field from Co. It was concluded that ScCo 2 is an exchange enhanced Pauli paramagnet of the same kind of YCo 2 and LuCo 2 .
