Magnetic properties of the (Gd0.975Lu0.025)(5)Ge-4 alloy have been measured and compared with the parent Gd5Ge4 compound. Lu doping weakens the ferromagnetic interactions in Gd5Ge4 and this effect is much stronger than what may be expected from a simple dilution effect. An unusual magnetic frustration, likely induced by the kinetic arrest of the O(II) antiferromagnetic-O(I) ferromagnetic magnetostructural transformation as reported in the parent Gd5Ge4, has been observed.
