Abstract
The influence of particle rotation on the magnetic properties of BaFe1 0.4Co0.8Ti0.8O19 nanocrystalline powder is discussed. The time depende nce of the thermoremanence is analyzed in terms of T ln(t/tau(0)) scal ing, instead of the logarithmic approximation. The relaxation rate at low temperatures is discussed assuming that there exists a larger amou nt of lowest energy barriers than expected for a single log-normal dis tribution.
