Thanks! Of course i dont expect too. My particles are too small to have more than one domain. Guess that the best way to check first effect is to make lots of samples with different concentration of particles. For second - add more materials as matrixes. Third - try to warm glue b4 hardening. It is a lot=\ going to find some information first, will be grateful if someone helps.

Hi! Need help=( Just noticed a small difference in B-H curve of FeOx nanoparticles placed in paraffin and polymer glue. In particular, coercivity increased(in superparamagnetic particles) in glue comparing to paraffin. For me it sounds quite crazy and it appears to ruin the precision of measuring B-H curve of particles. Measured using VSM. So the questions are - is it normal? How can one predict this effect? Or the VSM needs verification? Thanks in advance.
