S. Galaj et al., MAGNETOMETRIC ANALYSIS OF A NEW CLASS OF COPOLYMER MAGNETS BASED ON AMINONAPHTHALENESULFONIC ACIDS, Journal of magnetism and magnetic materials, 144, 1995, pp. 1445-1446
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.
