This procedure has been applied to other symmetries such as the well-known Preyssler anion [LnP5W30O110]12-, LnW30 (Figure 2.Id) [9]. This POM has a central coordination site with an unusual, fivefold axial symmetry. In spite of the low symmetry provided by this anion, we have observed that the dysprosium and holmium derivatives behave as SMMs, exhibiting slow relaxation of the magnetization. The remarkable difference between this system and the previous...

There are not many uses for dysprosium. Scientists continue to experiment with it as a possible alloy metal (it has a high melting point) to be mixed with steel to make control rods that absorb neutrons in nuclear reactors. There are only a few commercial uses for dysprosium, such as a laser material and as a fluorescence activator for the phosphors used to produce the colors in the older TV and computer cathode ray tubes (CRTs). When combined with steel or nickel as an alloy, it makes strong magnets. 

Gadolinium and dysprosium, both elements of the lanthanide family, differ in the electronic occupancy of their f-shells. As a result, they are very similar chemically but very different magnetically. The relaxivity 1/Tx of Dy-DTPA is as low as 0.1 1/mol s However, dysprosium has a pronounced ability to influence transiently the residual magnetic susceptibility of tissues as it passes through. This effect of Dy-DTPA seems to be ideal for cerebral perfusion imaging and may be useful for the quantitation of partial occlusions and reperfusion. 

Several lanthanide metals can be found in certain types of magnetic data storage disks for computers. Gadolinium, terbium, and dysprosium are among the elements often sandwiched with iron and cobalt in thin layers to make these devices. 

It should be noted that the intermediate state was detected by a magnetic technique in MWO4 [13], and by a magnetooptical one in dysprosium orthoferrite [11].
