Resistivity measurements have been carried out for Y(Mn1-xCux)2 compounds with values of x of
0, 0.04, 0.07, 0.10, 0.20 and 0.30 in the temperature range from 4.2 up to 300 K at zero pressure and for
YMn2 under a pressure of 2 kbar. TN has been found to decrease rapidly by applying external pressure as
well as by applying a chemical pressure caused by a partial substitution of Mn atoms by Cu atoms. ?? 1992.
