Anomalous ferromagnetism of oxidized polypropylene
Smirnova S. G. , Demicheva O. V., Grigorov L. N.
The synthesis of an organic polymer ferromagnet on the basis of oxidized atactic polypropylene is reported. A fundamentally new phenomenon has been discovered: an abrupt transition of the material from a paramagnetic state to a ferromagnetic state, induced by a magnetic field.
