|Title:||Effect of the chemical substitution on the magnetic properties of UGe2|
da Silva, LM
|Abstract:||Magnetic results for the U(Ge1-ySny)(2) and (Y1-xUx)Ge-2 series of compounds are reported. The magnetization for U(Ge1-ySny)(2) shows a ferromagnetic (FM) state for y <= 0.6 but above this concentration the compounds order antiferromagnetically. For (Y1-xUx)Ge-2, starting from the U side, the system is FM and below x = 0.8 it exhibits a complex behavior: for x > 0.4 a reentrant spin-glass phase is observed; for x = 0.2 and x = 0.3 we found a non-Fermi-liquid behavior and at x 0 it is a superconductor. A magnetic phase diagram is presented for both series. (C) 2003 Elsevier B.V. All rights reserved.|
