Abstract
The magnetic and transport properties of Fe${}_{2}$VGa doped with metal M (M = Rh and Ti) have been obtained from the analysis of ac magnetic susceptibility ${\ensuremath{\chi}}_{ac}$, magnetization $M$ vs magnetic field, specific heat $C$, and electrical resistivity $\ensuremath{\rho}$. The results provide evidence for the formation of a spin-glass state at ${T}_{f}\ensuremath{\sim}6$ K, resulting from an atomic disorder. Short-range magnetic correlations manifested at $Tg{T}_{f}$ as anomalies of the low magnetic field ac magnetic susceptibility and specific-heat data are believed to be related to a Griffiths-like phase in Fe${}_{2}$V${}_{1\ensuremath{-}x}$M${}_{x}$Ga at $xl{x}_{c}\ensuremath{\sim}0.15$.
