Title : Pseudo magnetic field, with a strength of hundreds of tesla in thenanographite films
Abstract:
Report describes some unusual electromagnetics things of nanocrystalline graphite (NG) films. One of them is conductivity switching from high to very small value when the transport current goes beyond a certain critical magnitude (this may be used in electrical commutator) In the report, an attempt is made to explain the appearance of coherent optical radiation upon conductivity switching in NG films by the occurrence of pseudo magnetic field in the NG film.
