Journal ArticleDOI
Low-frequency noise and tunneling magnetoresistance in Fe(110)∕MgO(111)∕Fe(110) epitaxial magnetic tunnel junctions
Ruben Guerrero,Farkhad G. Aliev,R. Villar,Jan O. Hauch,Michael Fraune,Gernot Güntherodt,Karsten Rott,Hubert Brückl,Günter Reiss +8 more
TL;DR: In this article, tunneling magnetoresistance (TMR), current-voltage (I-V) characteristics and low-frequency noise in epitaxially grown Fe(110)∕MgO(111) ∕Fe(110), magnetic tunnel junctions (MTJs) with dimensions from 2×2 to 20×20μm2 were investigated.
Journal ArticleDOI
Temperature dependent resistance of magnetic tunnel junctions as a quality proof of the barrier
Ulrich Rüdiger,Raffaella Calarco,U. May,K. Samm,Jan O. Hauch,Harish M. Kittur,Martin Sperlich,Gernot Güntherodt +7 more
TL;DR: In this article, the quality of the AlOx barrier has been proven by x-ray photoelectron spectroscopy and temperature dependent tunneling magnetoresistance (TMR) measurements.
Journal ArticleDOI
Electronic structure of the Fe3O4(111) surface
Yuriy Dedkov,M. Fonin,Denis V. Vyalikh,Jan O. Hauch,Serguei L. Molodtsov,Ulrich Rüdiger,Gernot Güntherodt +6 more
TL;DR: The surface electronic band structure of thin, well-ordered epitaxial films has been investigated at room temperature by means of angle-resolved photoelectron spectroscopy using synchrotron radiation as discussed by the authors.
Journal ArticleDOI
Temperature-dependent magnetoresistance of magnetic tunnel junctions with ultraviolet light-assisted oxidized barriers
U. May,K. Samm,Harish M. Kittur,Jan O. Hauch,Raffaella Calarco,Ulrich Rüdiger,Gernot Güntherodt +6 more
TL;DR: In this paper, an ultraviolet light-assisted oxidation process of the AlOx barrier has been optimized by in situ x-ray photoelectron spectroscopy, in conjunction with temperature-dependent tunneling magnetoresistance measurements.
Journal ArticleDOI
Characterization of epitaxial growth of Fe(110) on (11-20) sapphire substrates driven by Mo(110) seed layers
TL;DR: In this paper, the growth of bcc Fe(1/1/0) thin films on an Al 2 O 3 (1/ 1/−2/0)-substrate using Mo(1 /1/ 0) seed layers has been investigated by reflection high energy electron diffraction (RHEED) in reciprocal space and by scanning tunneling microscopy in real space.
