Molecular nanomagnets (MNMs) comprise clusters of exchange coupled transition metal ions which often have a negative anisotropy constant, favoring a ground state with a large electronic spin. MNMs have been extensively and successfully probed using conventional techniques but muon measurements have been hard to interpret. We have recently shown that muon spins are relaxed by the electronic spins of MNMs which , in turn, are relaxed by incoherent nuclear magnetic fluctuations. We now wish to examine the muon response at a level crossing in MNMs. Cr8Cd has a level crossing at 2.3 T placing it within the range of HiFi. The proposed measurements should allow us to assess the role of the nuclear magnetism close to the crossing, which is important since these nuclear effects have been proposed to bring levels into resonance and allow quantum tunneling of the magnetization.
