    "abstract": "We discuss the contribution of the material type in metal wires to the\nelectromagnetic fluctuations in magnetic microtraps close to the surface of an\natom chip. We show that significant reduction of the magnetic noise can be\nachieved by replacing the pure noble metal wires with their dilute alloys. The\nalloy composition provides an additional degree of freedom which enables a\ncontrolled reduction of both magnetic noise and resistivity if the atom chip is\ncooled. In addition, we provide a careful re-analysis of the magnetically\ninduced trap loss observed by Yu-Ju Lin et al. [Phys. Rev. Lett. 92, 050404\n(2004)] and find good agreement with an improved theory.",
