The quantum tunneling in a mononuclear Dy‐based single‐molecule magnet (SMM) can be drastically reduced, improving the capability of the molecule to store magnetic information. As O. Cador and co‐workers show in their Communication on page 1504 ff, this improvement is brought about by using isotopes of Dy III that do not have a nuclear magnetic moment and by dilution of the SMM in a diamagnetic matrix. Combined, these strategies lead to the opening of the hysteresis loop in zero field, and the relaxation time is increased.
