Defect-induced magnetism in TiO: An example of quasi 2D magnetic order with perpendicular anisotropy
Markus Stiller, Pablo D. Esquinazi
Magnetic order at room temperature induced by atomic lattice defects, like vacancies, interstitials or pairs of them, has been observed in a large number of different nonmagnetic h…
Influence of surface band bending on a narrow band gap semiconductor: Tunneling atomic force studies of graphite with Bernal and rhombohedral stacking orders
Regina Ariskina, Michael Schnedler, Pablo D. Esquinazi +7
Tunneling atomic force microscopy (TUNA) was used at ambient conditions to measure the current-voltage (-) characteristics at clean surfaces of highly oriented graphite sampl…
Record-Breaking Magnetoresistance at the Edge of a Microflake of Natural Graphite
Christian E. Precker, Jose Barzola-Quiquia, Pablo D. Esquinazi +5
Placing several electrodes at the edge of a micrometer-size Sri Lankan natural graphite sample at distances comparable to the size of the internal crystalline regions, we found rec…
Nonintrinsic origin of the magnetic-field-induced metal-insulator and electronic phase transitions in graphite
José Barzola-Quiquia, Pablo D. Esquinazi, Christian E. Precker +5
A detailed magnetoresistance study of bulk and microflake samples of highly oriented pyrolytic graphite with a thickness of 25 m to 23~nm reveals that the usually observed field…
Influence of Interfaces on the Transport Properties of Graphite revealed by Nanometer Thickness Reduction
Mahsa Zoraghi, José Barzola-Quiquia, Markus Stiller +2
We investigated the influence of thickness reduction on the transport properties of graphite microflakes. Using oxygen plasma etching we decreased the thickness of highly oriented…
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…
