    "abstract": "We describe an experiment in which Bose-Einstein condensates and cold atom\nclouds are held by a microscopic magnetic trap near a room temperature metal\nwire 500 $\\mu$m in diameter. The ensemble of atoms breaks into fragments when\nit is brought close to the ceramic-coated aluminum surface of the wire, showing\nthat fragmentation is not peculiar to copper surfaces. The lifetime for atoms\nto remain in the microtrap is measured over a range of distances down to $27\n\\mu$m from the surface of the metal. We observe the loss of atoms from the\nmicrotrap due to spin flips. These are induced by radio-frequency thermal\nfluctuations of the magnetic field near the surface, as predicted but not\npreviously observed.",
