Effects of size and surface anisotropy on thermal magnetization and hysteresis in the magnetic clusters

Huang, Z.; Chen, Z.; Li, S.; Feng, Q.; Zhang, F.; Du, Y. - In: The European Physical Journal B - Condensed Matter and … 51 (2006) 1, pp. 65-73

Based on Monte Carlo simulation, the spin configurations, thermal magnetization and hysteresis loops of the clusters coated by the surface shell with radial anisotropy are studied. Interestingly, a new multidomain containing a few of subdomains whose easy directions are along those of the...
