Magnetically modulated microwave absorption (MMMA) measurements at low magnetic fields on the ferromagnetic state of [TDAE]C-60
The ferromagnetic state and reported superconductivity of [TDAE]C-60 (where TDAE is tetrakis(dimethylamino)ethylene, see Figure) are investigated by magnetically modulated microwave absorption (MMMA). The results are compared with those reported using alternative physical measurement techniques, and a hypothesis proposed to explain the observed behavior. No evidence for superconductivity is found.
