High-field and high-temperature magnetoresistance reveals the superconducting behaviour of the stacking faults in multilayer graphene
Christian E. Precker, José Barzola-Quiquia, Mun K. Chan +2
In spite of 40 years of experimental studies and several theoretical proposals, an overall interpretation of the complex behavior of the magnetoresistance (MR) of multilayer graphe…
Local Magnetic Measurements of Trapped Flux Through a Permanent Current Path in Graphite
Markus Stiller, Pablo D. Esquinazi, Jose Barzola-Quiquia +1
Temperature and field dependent measurements of the electrical resistance of different natural graphite samples, suggest the existence of superconductivity at room temperature in s…
Evidence for room temperature superconductivity at graphite interfaces
Pablo D. Esquinazi, Christian E. Precker, Markus Stiller +4
In the last 43 years several hints were reported suggesting the existence of granular superconductivity above room temperature in different graphite-based systems. In this paper so…
Local magnetic measurements of permanent current paths in a natural graphite crystal
Markus Stiller, Pablo D. Esquinazi, Christian E. Precker +1
A recently reported transition in the electrical resistance of different natural graphite samples suggests the existence of superconductivity at room temperature. To check whether…
Identification of a possible superconducting transition above room temperature in natural graphite crystals
Christian E. Precker, Pablo D. Esquinazi, Ana Champi +11
Measuring with high precision the electrical resistance of highly ordered natural graphite samples from a Brazil mine, we have identified a transition at 350~K with 40~…
