Induced Magnetic Order by Ion Irradiation of Carbon-Based Structures
P. Esquinazi, R. Höhne, K. -H. Han +5
In this chapter we review the magnetic effects produced by proton irradiation on graphite, disordered carbon and fullerene films. The advantage of proton irradiation is twofold: it…
Induced Magnetic Ordering by Proton Irradiation in Graphite
P. Esquinazi, D. Spemann, R. Höhne +3
We provide evidence that proton irradiation of energy 2.25 MeV on highly-oriented pyrolytic graphite samples triggers ferro- or ferrimagnetism. Measurements performed with a superc…
The origin of paramagnetic magnetization in field-cooled YBa2Cu3O7 films
D. A. Luzhbin, A. V. Pan, V. A. Komashko +4
Temperature dependences of the magnetic moment have been measured in YBa_2Cu_3O_{7-δ} thin films over a wide magnetic field range (5 <= H <= 10^4 Oe). In these films a paramagnetic…
A Field-Effect-Transistor from Graphite: No Effect of Low Gate Fields
H. Kempa, P. Esquinazi
Inspired by the striking similarities between the metal-insulator transitions in graphite and Si-MOSFET's and the recent attention to charge doping in carbon-based materials, we ha…
Metal-Insulator-Metal Transitions, Superconductivity and Magnetism in Graphite
Y. Kopelevich, P. Esquinazi, J. H. S. Torres +4
This article reviews recent results of magnetotransport and magnetization measurements performed on highly oriented pyrolitic graphite (HOPG) and single crystalline Kish graphite s…
Comment on ``New Vortex-Matter Size Effect Observed in BiSrCaCuO"
Y. Kopelevich, P. Esquinazi
The Letter of Wang et al. \cite{wan} is related to the recently discovered vanishing of the second magnetization peak (SMP) in high- superconductors reducing the sample size \…
