Unconventional superconductors have specific signatures in their magnetic properties, such as intrinsic magnetization at interfaces and around defects and fractional and multiquanta vortices, with much attention focused on heavy fermion and high-Tc superconductors. Here, we report the observation of highly anomalous magnetization in β-PdBi2, a layered superconductor previously shown to exhibit a magnetic field-induced transition from s-wave to nodal p-wave superconductivity at a transition field H^*∼0.1 T (HC1
