K. Takeda et al., PRESSURE-INDUCED REDUCTION OF THE CURIE-TEMPERATURE OF THE ORGANIC FERROMAGNET P-NPNN, Journal of magnetism and magnetic materials, 144, 1995, pp. 1451-1452
Under hydrostatic pressure, a drastic reduction of the Curie temperatu
re T-C(p) of beta-phase p-NPNN, a genuine organic ferromagnet, has bee
n found; from T-C(p(0)) = 0.61 K (p = p(0) = 0.001 kbar) to T-C(p) = 0
.35 K (p = 7.2 kbar), for example. The results are discussed in compar
ison with the positive effect of pressure on the Neel temperatures of
organic antiferromagnets.
