Abstract
Temperature dependence of hyperfine fields for 111Cd in (Y 1−xUx)Mn 2 alloys have been studied by perturbed angular correlation spectroscopy. Single phase alloys having C-15 cubic structure synthesized for x < 0.1 show contraction of the unit cell. The magnetic hyperfine field as well as the transition temperature show steep decline with increasing U content, while the quadrupole interaction frequency show the opposite behavior. As an important feature our results reveal that doping U in YMn 2 changes the nature of the magnetic phase transition from first to second order.
