Abstract
Antiferromagnetic transition in thermally evaporated Mn-V alloys has been studied using resistivity-temperature measurements from 300 to 1.4 K. Resistivity-temperature behaviour typical of bulk \alpha -Mn rich specimen is obtained with 0.05 at % V in Mn. The Néel point is shifted to 86 \pm 1 K from the value of 90 \pm 1 K known for pure \alpha -Mn. The Néel point is shifted further to lower values as the concentration of V in Mn increases. Below the temperature corresponding to the low temperature resistivity minimum, the resistivity obeys a T^2 law, suggesting that vanadium impurities in the manganese film gives rise to a distortion of the magnetic moment of the manganese atoms and thus leading to spin fluctuation scattering on the conduction electrons.
