Magnetic domain formation in La1-xSrxMnO3 nanowires studied with resonant soft x-ray scattering
… magnetic domain formation in La(1-x)Sr(x)MnO3 (LSMO) nanowires. In theory, a 1D ferromagnetic wire is not capable of forming a single domain without an applied field. Therefore, it is meaningful to study how the spatial confinement contributes towards magnetic domain formation. In particular, …

Control of Superconductivity in Cuprate/Manganite Heterostructures
… to minimum thicknesses of 3nm for both YBCO and LSMO. Using spin injection, via a ferromagnet, to create a spin imbalance in the superconductor, a suppression of superconducting critical current was observed with increasing injection current. However, the exact cause of this suppression could not …
