Magneto-structural phase transitions and two-dimensional spin waves in graphite
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
We have previously found experimental evidence for several quantum phenomena in oxygen-ion implanted of hydrogenated graphite: ferromagnetism, antiferromagnetism, paramagentism, tr…

Flat-band energy analysis of the temperature-dependent superconducting gap for hydrogenated graphite fibers found from nonlocal electrical conductance experimental data
Nadina Gheorghiu, Charles R. Ebbing, Timothy J. Haugan
Experimental evidence of novel phenomena in hydrogenated graphite fibers is found. An indirect excitonic mechanism is likely leading to a SC state below the temperature Tc = 50 K,…
