Theory for Tunnel Magnetoresistance Oscillation
Keisuke Masuda, Thomas Scheike, Hiroaki Sukegawa +3
The universal oscillation of the tunnel magnetoresistance (TMR) ratio as a function of the insulating barrier thickness in crystalline magnetic tunnel junctions (MTJs) is a long-st…
Fully epitaxial fcc(111) magnetic tunnel junctions with a Co90Fe10/MgAlO/Co90Fe10 structure
Jieyuan Song, Thomas Scheike, Cong He +5
Magnetic tunnel junctions (MTJs) with bcc(001)-type structures such as Fe(001)/MgO(001)/Fe(001), have been widely used as the core of various spintronic devices such as magnetoresi…
Granular superconductivity at room temperature in bulk highly oriented pyrolytic graphite samples
T. Scheike, P. Esquinazi, A. Setzer +1
We have studied the magnetic response of two bulk highly oriented pyrolytic graphite (HOPG) samples with different internal microstructure. For the sample with well defined interfa…
Can doping graphite trigger room temperature superconductivity? Evidence for granular high-temperature superconductivity in water-treated graphite powder
T. Scheike, W. Böhlmann, P. Esquinazi +3
Trying to dope graphite flakes we found that the magnetization of pure, several tens of micrometers grain size graphite powder and after a simple treatment with pure water shows cl…
Evidence of Josephson-coupled superconducting regions at the interfaces of Highly Oriented Pyrolytic Graphite
A. Ballestar, J. Barzola-Quiquia, P. Esquinazi
Transport properties of a few hundreds of nanometers thick (in the graphene plane direction) lamellae of highly oriented pyrolytic graphite (HOPG) have been investigated. Current-V…
