Many magnetocaloric materials exhibit magnetic hysteresis
, where material properties are dependent on the history of the magnetic field.
3.2 Magnetic Hysteresis
and Susceptible Material Signals
The Polder tensor components relate to frequency range, magnetic resonance, the magnetic hysteresis
loop, geometrical dimensions and other ferromagnetic material properties.
Efficient relaxation processes can significantly lower the temperature at which magnetic information is retained, based on what would be predicted solely from consideration of an isolated Ln SMM, and thus these must be investigated to make progress.We have recently found that Ln cations bonded only to two five-membered carbon atom rings in an axial arrangement give a SMM for which the highest temperatures at which magnetic hysteresis
, a memory effect that is essential for data storage, has ever been observed.

and constitutive nonlinearities are fundamental properties of all ferromagnetic materials, which exhibit nonlinear behavior where the permeability/susceptibility is a function of the magnetic field intensity.
In this study, the room temperature magnetic hysteresis
loop of the calcined products of LDH (ZnO and Zn[Fe.sub.2][O.sub.4]) shows a paramagnetic behavior as shown in Figure 5.
