hi, could anyone tell what a quadrupole quadrupolar ordering state or an antiferroquadrupolar ordering state is? i am a collage student, i have access to a collage library but can find very little. it seems to be a very specialist subject and information is hard to come by. i understand what antiferromagnetic ordering is, and i expect antiferroquadrupolar is the same but with molecules that possess 4 dipoles or something like that? am i even close?
