Abstract
Magnetic properties of the (Gd0.975Lu0.025)5 Ge 4 alloy have been measured and compared with the parent Gd5 Ge 4 compound. Lu doping weakens the ferromagnetic interactions in Gd5 Ge 4 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 Gd5 Ge 4, has been observed.Keywords
