Abstract: It is found experimentally that the introduction of

1 %

$1\%$ Fe in the CuGeO

_{3}

$_3$ matrix gives rise to a strong disorder in the magnetic subsystem and leads to an appearance of the

χ \sim 1 / T^{α}

$\chi \sim 1/T^\alpha$ , (

α \approx 0.36

$\alpha \approx0.36$ ) low-temperature asymptotic form for magnetic susceptibility over a wide temperature range

1.7 \leq T \leq 30

$1.7\leq T\leq30$ K. A model attributing this anomaly to the suppression of spin-Peierls state as a result of the formation of the quantum critical point is proposed.
