In general, conventional superconductivity and magnetism are competing phenomena. In some alloys this competition is a function of the concentration of the elements. Here we show that in the palladium alloys Pd1−c(H/D/T)c (Pd-ides) the increase in the concentration c of the ides: hydrogen, deuterium, tritium (H/D/T), lowers the predicted magnetism of amorphous palladium (a-Pd) gradually, allowing superconductivity to appear for c≈40%. This magnetism explains why superconductivity does not manifest for smaller values of c (c≤40%) in these Pd alloys. Also, these results validate indirectly our predicted magnetism in the amorphous/porous palladium (a/p-Pd). The understanding of the interplay between magnetism and superconductivity may contribute to the comprehension of the magnetic behavior in materials, especially in high Tc superconductors, with the corresponding implications.
