Single-molecule magnets discovery

The discovery that certain metalloxo clusters can sustain a remanent magnetization prompted interest in the synthesis of new single-molecule magnets as potential media for high-density information storage. Unfortunately, the broad... 

Of comparable importance was the subsequent discovery that Ams = + 2 transitions could be detected at low fields for triplet molecules in random orientations in rigid media (van der Waals and de Groot, 1959, 1960). These are best observed with the apparatus modified so that the static and oscillating magnetic fields are parallel, but if weak spectra can be detected with the normal arrangement of static and oscillating fields perpendicular to each other then the combined results are almost as informative as those from single crystal studies.
