Giant and time-dependent magnetocaloric effect in high-spin molecular magnets
We have measured and calculated the magnetocaloric effect in macroscopic
samples of oriented high-spin molecular clusters like Mn12 and Fe8 as a
function of the temperature and both the intensity and the sweeping rate of the
applied magnetic field. We have observed a high magnetic entropy variation
around the blocking temperature of the magnetic moment of molecules and
calculated the shift of the entropy variation and cooling temperature, with the
sweeping rate of the magnetic field.Comment: 10 pages, 3 figure
