Abstract: There are numerous theoretical candidates for dark matter significantly heavier than the WIMP scale (~100GeV), yet such models are less explored by experimental efforts. In this talk, I will discuss our progress searching for ultraheavy dark matter above 1 PeV in mass using a magnetically levitated setup with a 0.3mg test mass and less than 100aN/rtHz of force noise. I will present the estimated sensitivity and discuss our on-going experimental campaign and data analysis. We expect to have leading sensitivity in parts of the parameter space, and our work represents the first time a maglev sensor is being used to search for ultraheavy dark matter.
