The role of anharmonic phonons in under-barrier spin relaxation of single molecule magnets

Single molecule magnets exhibit faster spin relaxation rates than expected from models based on tunnelling through the relaxation barrier. Here, the authors show, using first principles calculations, that anharmonic spin-phonon interactions may explain the under-barrier spin relaxation.
