Anomalous properties in a rare correlated ferromagnet Nd$_{2}$PdSi$_{3}$
ORAL
Abstract
The compound Nd$_{2}$PdSi$_{3}$ belongs to an AlB$_{2}$-derived ternary family (hexagonal structure, space group $P$6/\textit{mmm}) showing many exotic properties [1-3]. This compound is considered to order ferromagnetically (\textit{\textless }16 K), unlike other members of this series ordering antiferromagnetically. The magnetic ordering temperature ($T_{0})$ is significantly enhanced with respect to the de Gennes--scaled value [3]. Recently, based on polycrystalline study the effects of Nd (4$f) $hybridization on the magnetism is discussed, which is rare in an Nd-based intermetallic compound [3]. We have grown single crystals of Nd$_{2}$PdSi$_{3}$ using Czochralski method in a tetra arc furnace. We would like to present neutron scattering, transport, magnetic, and thermal properties on Nd$_{2}$PdSi$_{3}$ and discuss Nd (4$f) $hybridization.\\[4pt] [1] S. R. Saha \textit{et al}. , Phys. Rev.
