- Abstract: I present the results of the SHAFT experiment at Boston University to search for axion-like dark matter in the mass range from 12 peV to 12 neV. The experiment is sensitive to the oscillating magnetic field that would be sourced by an axion-like dark matter halo of our Galaxy interacting with a strong static magnetic field in the lab. We employ toroidal ferromagnetic cores made of powdered iron-nickel alloy to enhance the static magnetic field by a factor of 24. Using superconducting quantum interference devices (SQUIDs), we achieve a magnetic sensitivity of 150 aT/rtHz. This sensitivity allows us to improve, over a part of our mass range, the existing laboratory limits on the electromagnetic coupling of axion-like dark matter.
