Status of DMRadio-50L and DMRadio-m\(^3\)

Recent theoretical advancements have made the QCD axion a stronger dark matter candidate, especially in the sub-\(\mu\text{eV}\) range. While cavity haloscopes have made significant progress in excluding QCD axions in the \(1 - 100\ \mu\text{eV}\) region, the \(1 \text{ peV} - 1\ \mu\text{eV}\) region remains unexplored. The DMRadio program consists of a series of experiments designed to probe low mass axions. DMRadio-50L uses a 1 T average field toroidal magnet and a high-Q LC-oscillator with target sensitivity to axions of \(g_{a\gamma\gamma}
