Evolution of superconductivity and magnetic order in heavy fermion superconductor Ce(Pt1-xNix)3Si

A substitution of Pt/Ni has been performed in the heavy fermion superconductor CePt3Si. The isoelectronic exchange of Pt by Ni causes a non-monotonic change of the lattice parameters as well as of the volume of the crystallographic unit cell. Results of the substitutions are slight changes of the ma...

Beschreibung
Zusammenfassung:	A substitution of Pt/Ni has been performed in the heavy fermion superconductor CePt3Si. The isoelectronic exchange of Pt by Ni causes a non-monotonic change of the lattice parameters as well as of the volume of the crystallographic unit cell. Results of the substitutions are slight changes of the magnetic ordering temperature and the onset temperature of superconductivity.
