Abstract
SANS has been used to study magnetic correlations in Y (Co1-xMnx)2 alloys with x = 0.05, 0.1 and 0.2. Contrary to previous reports no evidence of ferromagnetism is observed. Instead the correlation range is found to increase monotonically with decreasing temperature reaching only 90 Å at 2 K.
