Abstract
Recently, a new class of copolymer based on aminonaphthalenesulfonic a cid and aniline were synthesized. By means of a VSM, an AGFM and a SQU ID, it was shown that these materials are ferromagnetic, above room te mperature. These results, consistent with temperature dependent EPR te sts and magneto-optic experiments, support the achievement of high tem perature magnets (T < 600 K) using only light elements of Mendeleev cl assification, considered as a scientific challenge.
