Magnetic properties are presented for the Eu2Ag15-xAl2+x (x = 1.92 and 2.51), Eu3Ag13-xAl8+x (x = 0.64), EuAg6+xAl7-x (x = 0.46), EuAg5-xAlx (x = 0.5 and 1.5), EuAg15-xGa2+x (x = 1.4 and 2) and EuAg5-xGax (x = 0.5 and 1) alloys. In all investigated compounds a divalent state of Eu ions was deduced from the results obtained for temperature dependencies of their magnetic susceptibilities, as well as the results derived for their field dependencies of isothermal magnetizations recorded at 1.9 K. At low fields, and low temperatures, magnetic phase transitions to magnetically ordered states occur for all compounds under study except of EuAg6.46Al6.54, which stays in the paramagnetic state down to 1.9 K. Six compounds orders antiferromagnetically while further three reveal ferrimagnetic-like ordering with uncompensated net moments.
