Unravelling the origin of high-temperature magnetic bistability in dysprosocenium

Abstract: In the last 25 years the highest blocking temperature TB achieved for the best performing molecular nanomagnets has only reached few K. The situation has recently changed abruptly, with observation of magnetic hysteresis at 60 K in the dysprosocenium nanomagnet. Magnetic measurements and ab initio calculations suggest that the origin of this astonishing increase in TB is related to the coupling of the molecular spin with the constrained metal-ligand vibrational modes. We propose to use MERLIN to measure the phonon density of states and CF excitations to understand the origin of the high-temperature magnetic bistability of dysprosocenium and model its relaxation dynamics.
