Anomalous Enhancement of the Superconducting Transition Temperature in Electron-Doped Cuprate Heterostructures
K. Jin, P. Bach, X. H. Zhang +7
The superconducting transition temperature of multilayers of electron-doped cuprates, composed of underdoped (or undoped) and overdoped La% CeCuO (LCCO)…
Resonant soft x-ray scattering from La(1-x)Sr(x)MnO(3) quantum wire arrays
X. M. Chen, E. M. Spanton, S. Wang +9
We describe a strategy for using resonant soft x-ray scattering (RSXS) to study the electronic structure of transition metal oxide quantum wires. Using electron beam lithography an…
Strain amplification of the 4k chain charge instability in SrCuO
A. Rusydi, P. Abbamonte, H. Eisaki +7
We have used resonant soft x-ray scattering (RSXS) to study the misfit strain in SrCuO (SCO), a cuprate that contains both doped spin ladders and spin chains,…
Experimental evidence of paired hole states in model high- compounds
A. Rusydi, P. Abbamonte, M. Berciu +6
The distribution of holes in SrCaCuO (SCCO) is revisited with semi-emperical reanalysis of the x-ray absorption (XAS) data and exact-diagonalized cluster…
Heat accumulation and all-optical switching by domain wall motion in Co/Pd superlattices
F. Hoveyda, E. Hohenstein, S. Smadici
All-optical switching by domain wall motion has been observed in Co/Pd superlattices. Heat accumulation is part of the switching process for our experimental conditions. Numerical…
Graded Orbital Occupation near Interfaces in a La2NiO4 - La2CuO4 Superlattice
S. Smadici, J. C. T. Lee, J. Morales +5
X-ray absorption spectroscopy and resonant soft x-ray reflectivity show a non-uniform distribution of oxygen holes in a La2NiO4 - La2CuO4 (LNO-LCO) superlattice, with excess holes…

Pump-probe experiments and polarizing microscopy are applied to examine temperature and heat flow in metallic magnetic superlattices on glass substrates. A model of heat diffusion…
Superconducting transition at 38 K in insulating-overdoped La2CuO4-La1.64Sr0.36CuO4 superlattices: Evidence for interface electronic redistribution from resonant soft x-ray scattering
S. Smadici, J. C. T. Lee, S. Wang +5
We use resonant soft x-ray scattering (RSXS) to quantify the hole distribution in a superlattice of insulating La2CuO4 (LCO) and overdoped La_{2-x}Sr_{x}CuO4 (LSCO). Despite its no…
Demagnetizing fields in all-optical switching
F. Hoveyda, E. Hohenstein, R. Judge +1
Time-resolved pump-probe measurements show ultrafast and heat accumulation demagnetization in Co/Pd superlattices on glass substrates. A model of demagnetizing fields and micromagn…
Ultrafast demagnetization at high temperatures
F. Hoveyda, E. Hohenstein, R. Judge +1
Time-resolved pump-probe measurements were made at variable heat accumulation in Co/Pd superlattices. Heat accumulation increases the baseline temperature and decreases the equilib…
Interface Ferromagnetism in a SrMnO3/LaMnO3 Superlattice
S. Smadici, B. B. Nelson-Cheeseman, A. Bhattacharya +1
Resonant soft x-ray absorption measurements at the O K edge on a SrMnO3/LaMnO3 superlattice show a shoulder at the energy of doped holes, which corresponds to the main peak of reso…
Spatially modulated "Mottness" in La2-xBaxCuO4
P. Abbamonte, A. Rusydi, S. Smadici +3
Stripe phases were predicted to arise in doped antiferromagnets through competition between magnetism and the kinetic energy of mobile carriers (typically holes). In copper-oxides…
