Tiffany S. Santos,Jagadeesh S. Moodera,Karthik V. Raman,Ezana Negusse,J. Holroyd,J. Dvorak,M. Liberati,Yves Idzerda,Elke Arenholz +8 more
TL;DR: In this article, Schiller et al. determined a large exchange splitting of the conduction band in ultrathin films of the ferromagnetic semiconductor EuO by fitting the currentvoltage characteristics and temperature dependence to tunneling theory.

Determining Exchange Splitting in a Magnetic Semiconductor by Spin-Filter Tunneling
Tiffany S. Santos,Jagadeesh S. Moodera,K. Venkataraman,Ezana Negusse,J. Holroyd,J. Dvorak,M. Lierati,Yves Idzerda,Elke Arenholz +8 more
TL;DR: A large exchange splitting of the conduction band in ultrathin films of the ferromagnetic semiconductor EuO was determined quantitatively, by using EUO as a tunnel barrier and fitting the current-voltage characteristics and temperature dependence to tunneling theory.

Effect of electrode and EuO thickness on EuO-electrode interface in tunneling spin filter
Ezana Negusse,J. Holroyd,M. Liberati,J. Dvorak,Yves Idzerda,Tiffany S. Santos,Jagadeesh S. Moodera,Elke Arenholz +7 more
TL;DR: In this paper, the effect of electrode material and EuO film thickness on the interface between the two was studied by decomposing the x-ray absorption spectroscopy (XAS) spectra of the samples with different electrodes against the reference euO and eu2O3 spectra, the relative fraction of these two species was quantified.

Properties of thin film europium oxide by x-ray magnetic circular dichroism
TL;DR: In this paper, the authors measured magnetic circular dichroism as a function of temperature for the EuO M5 and M4 absorption edges in single-crystal thin films and found that the M5 edge is resolved into two major features, one with the same helicity dependence as the M4 edge, and one with opposite dependence.
