Larger anisotropy energy

Figure 9.1 shows the relationship between saturation moment and anisotropy energy for various candidate magnetic materials. The larger anisotropy energy... 

Even for applied magnetic fields below 1 T, the Zeeman energy may be larger than the anisotropy energy. Above the blocking temperature application of a... 

For large super-paramagnetic crystals or for crystals with a very high anisotropy constant (12), the anisotropy energy is larger than the thermal energy, which maintains the direction of the crystal magnetic moment very... 

Note that the dependence involving the excited state lifetime means that anisotropy cannot be accurately determined for the donor in doubly labelled molecules that display FRET, as the energy transfer is an additional relaxation pathway and so reduces the excited state lifetime resulting in apparently larger anisotropies. 

The emission spectra of the unbound TPPS display a two-banded feature with a main higher energy peak at 642 nm. In the case of a 1 1 molar ratio, this component is located at about 642-643 nm and shows very low fluorescence anisotropy. At higher CD concentration, the maxima move to 650 nm, displaying a larger anisotropy.
