Adjacent Fe-Vacancy Interactions as the Origin of Room Temperature Ferromagnetism in (InFe)O
R. J. Green, T. Z. Regier, B. Leedahl +5
Dilute magnetic semiconductors (DMSs) show great promise for applications in spin-based electronics, but in most cases continue to elude explanations of their magnetic behavior. He…
Tailoring the electronic transitions of NdNiO_3 films through (111)_pc oriented interfaces
S. Catalano, M. Gibert, V. Bisogni +8
Bulk NdNiO_3 and thin films grown along the pseudocubic (001)_pc axis display a 1st order metal to insulator transition (MIT) together with a Néel transition at T=200K. Here, we sh…
Electronic Transitions in Strained SmNiO_3 Thin Films
S. Catalano, M. Gibert, V. Bisogni +10
Nickelates are known for their metal to insulator transition (MIT) and an unusual magnetic ordering, occurring at T=T_Néel. Here, we investigate thin films of SmNiO_3 subjected to…
Broken translational and rotational symmetry via charge stripe order in underdoped YBCO
R. Comin, R. Sutarto, E. H. da Silva Neto +7
Following the early discovery of stripe-like order in La-based copper-oxide superconductors, charge ordering instabilities were observed in all cuprate families. However, it has pr…
Observation of Wakefields and Resonances in Coherent Synchrotron Radiation
B. E. Billinghurst, J. C. Bergstrom, C. Baribeau +8
We report on high resolution measurements of resonances in the spectrum of coherent synchrotron radiation (CSR) at the Canadian Light Source (CLS). The resonances permeate the spec…
Electronic depth profiles with atomic layer resolution from resonant soft x-ray reflectivity
M. Zwiebler, J. E. Hamann-Borrero, M. Vafaee +8
The analysis of x-ray reflectivity data from artificial heterostructures usually relies on the homogeneity of optical properties of the constituent materials. However, when the x-r…
