SUPERPARAMAGNETIC-PARAMAGNETIC TRANSITION IN SMALL PARTICLES
Résumé
The paramagnetic state and the superparamagnetic regime of small particles of the granular system Fe64Cr16B20-Al2O3 have been studied by mean of magnetization and susceptibility and compared to the properties of the corresponding bulk metal. The evolution of the magnetic structure near and above Tc is the same for both compounds. Deductions upon the particle size have been attempted.
