Abstract

In the system (

{(V_{1 - x} {Ti}_{x})}_{2} O_{3}

, the antiferromagnetic insulating phase is suppressed for

x > 0.05

. The linear term in the heat capacity is very large (

γ = 192 \times 10^{- 4}

cal °

K^{- 2}

per mole of

V_{2}

O_{3}

), and the magnetic susceptibility at 4.2°K is 2 ×

10^{- 3}

emu

{mole}^{- 1}

giving a value

\frac{χ}{γ} = 1.8

. The results are interpreted as evidence for a strongly correlated metallic phase.
