What is the difference between blocking temperature and curie temperature in magnetic studies of nanoparticles?
I guess you’re showing off ! You know in a controlled experiment, there should be minimal difference, as partially explained in the web site below: “…Although the TRM furnace is equipped for maintaining a controlled atmosphere and this feature was used in this study, the process requires careful attention and is somewhat of a nuisance. Since I did not need to exceed the Curie temperature by much in these experiments, I could not rely on using equilibrium atmospheres to prevent sample oxidation since equilibration is unlikely to occur at such low temperatures. I tried to eliminating chemical change in the samples during the magnetic experiments by isolating the samples from the atmosphere. The method I chose was to seal the samples in evacuated quartz tubes to minimize the probability of chemical alteration and to provide self-buffering. The samples were then thermally cycled from room temperature to beyond their Curie temperature until their magnetic properties stabilized. ” ……..
