Abstract
Electrical resistivity (), Seebeck coefficient (S) and magnetic susceptibility ()
measurements as a function of temperature on the (Cr -xAlx) V alloy system, with 0 < x
are reported. Néel temperatures (TN) obtained from all these measurements decrease with Al
concentration, disappearing near x 1.5, again reappearing for x . (T) and S(T) for
samples with x 6.1 show weak anomalies making the determination of TN difficult. However,
these anomalies are sharply defined in (T), proving that it is an important tool in probing
antiferromagnetic in this system. The present results show that the addition of just 1 at.% V to
the Cr -xAlx alloy system suppresses antiferromagnetism in the concentration range
5 ≤ x ≤ . This behaviour is similar to that observed for the (Cr -xAlx) 5Mo5 alloy system.
