WebStudy on the blocking temperature of mixed magnetic films by Monte Carlo simulation J Nanosci Nanotechnol. 2009 Feb;9 (2):1640-3. doi: 10.1166/jnn.2009.c221. Authors Zhenzhen Weng 1 , Zhigao Huang Affiliation 1 College of Physics and Information Engineering, Fuzhou University, Fuzhou, 350002, China. PMID: 19441589 DOI: … WebThe transition temperature from ferromagnetism to superparamagnetism with no hysteresis behavior is referred to as the blocking temperature (Tb) and is defined by the relationship Tb=KuV/25k. Superparamagnetism is shown when the size of nanoparticles is below Dc, and the temperature is above the blocking temp.
