Bootstrapped Dimensional Crossover of a Spin Density Wave
Anjana M. Samarakoon, J. Strempfer, Junjie Zhang +8
Quantum materials display rich and myriad types of magnetic, electronic, and structural ordering, often with these ordering modes either competing with one another or 'intertwining…
Investigation of ferromagnetic domain behavior and phase transition at nanoscale in bilayer manganites
C. Phatak, A. K. Petford-Long, H. Zheng +3
Understanding the underlying mechanism and phenomenology of colossal magnetoresistance in manganites has largely focused on atomic and nanoscale physics such as double exchange, ph…
Minority-spin states and the degree of spin polarization in ferromagnetic metallic LaSrMnO ()
Z. Sun, Q. Wang, J. F. Douglas +10
Using angle-resolved photoemission spectroscopy (ARPES), we investigate the electronic band structure and Fermi surface of ferromagnetic LaSrMnO (…
Antiferromagnetic Domain Structure in Bilayer Manganite
M. García-Fernández, S. B. Wilkins, Ming Lu +5
We report a novel soft x-ray nanodiffraction study of antiferromagnetic domains in the strongly correlated bylayer manganite LaSrMnO. We find that the…
Response of acoustic phonons to charge and orbital order in the 50\% doped bilayer manganite LaSrMnO
F. Weber, S. Rosenkranz, J. -P. Castellan +7
We report an inelastic neutron scattering study of acoustic phonons in the charge and orbitally ordered bilayer manganite LaSrMnO. For excitation energies less than $15…
Driving magnetic order in a manganite by ultrafast lattice excitation
M. Först, R. I. Tobey, S. Wall +14
Optical control of magnetism, of interest for high-speed data processing and storage, has only been demonstrated with near-infrared excitation to date. However, in absorbing materi…
Signature of checkerboard fluctuations in the phonon spectra of a possible polaronic metal La1.2Sr1.8Mn2O7
F. Weber, N. Aliouane, H. Zheng +3
Charge carriers in low-doped semiconductors may distort the atomic lattice and trap themselves forming so-called small polarons. High carrier concentrations can lead to short range…
Surface effects on the orbital order in the single layered manganite La0.5Sr1.5MnO4
Y. Wakabayashi, M. H. Upton, S. Grenier +7
We report the first observation of `orbital truncation rods' -- the scattering arising from the termination of bulk orbital order at the surface of a crystal. The x-ray measurement…
Full Bulk Spin Polarization and Intrinsic Tunnel Barriers at the Surface of Layered Manganites
J. W. Freeland, K. E. Gray, L. Ozyuzer +5
Transmission of information using the spin of the electron as well as its charge requires a high degree of spin polarization at surfaces. At surfaces however this degree of polariz…
Scaling of the magnetoconductivity of silicon MOSFET's: evidence for a quantum phase transition in two dimensions
S. A. Vitkalov, Hairong Zheng, K. M. Mertes +2
For a broad range of electron densities and temperatures , the in-plane magnetoconductivity of the two-dimensional system of electrons in silicon MOSFET's can be scaled onto…
Hall Coefficient of a Dilute 2D Electron System in Parallel Magnetic Field
S. A. Vitkalov, H. Zheng, K. M. Mertes +2
Measurements in magnetic fields applied at a small angle with respect to the 2D plane of the electrons of a low-density silicon MOSFET indicate that the Hall coefficient is indepen…
Temperature-Dependence of the Resistivity of a Dilute 2D Electron System in High Parallel Magnetic Field
K. M. Mertes, Hairong Zheng, S. A. Vitkalov +2
We report measurements of the resistance of silicon MOSFETs as a function of temperature in high parallel magnetic fields where the 2D system of electrons has been shown to be full…
