Magnetoelastic/piezoelectric laminated structures for tunable remote contactless magnetic sensing and energy harvesting
In this letter, we report a method for a tunable magnetic field sensor based on the magnetoelastic coupling properties of a magnetoelastic/piezoelectric laminated composite structure. The magnetically...

Magnetization switching without charge or spin currents
We propose schemes of reversing the magnetization of a ferromagnet by electric fields alone, without charge or spin currents or external magnetic fields. The switching is triggered by picosecond manip...

Using x-ray magnetic dichroism, we characterize the magnetic order in La0.7Sr0.3MnO3(LSMO)/La0.7Sr0.3FeO3(LSFO) superlattices with six unit cell thick sublayers. The LSMO layers exhibit a reduced Curie temperature compared to the bulk while antiferromagnetic order in the LSFO layers persists up to the bulk Néel temperature. Moreover, we find that aligning the LSMO magnetization by a magnetic field within the (001) surface plane leads to a reorientation of the Fe moments as well maintaining a perpendicular orientation of Fe and Mn moments. This perpendicular alignment is due to the frustrated exchange coupling at the LSMO/LSFO interface. ©2009 American Institute of Physics

  13. Theoretical spectra were obtained from the electric-dipole allowed transitions between the ground state 3dn and the final state 2p53dn+1 in the presence of an effective exchange field gµBH=−0.1  eV. The ground and final state wave functions were calculated in intermediate coupling using Cowan's Hartree–Fock code with relativistic correction. The results were broadened by a Lorentzian line shape increasing from Gamma=0.1 to 0.15 eV for the L3 structure and Gamma=0.3 to 0.35 eV for the L2 structure to account for the intrinsic linewidth and a Gaussian of sigma=0.2  eV for the instrumental broadening. We used 10Dq=1.6  eV giving a total symmetric ground state 6A1. Covalency was included by reducing the Hartree–Fock values of the 3d-3d Coulomb interaction to 60%, while the Slater integrals for the 2p-3d interaction were scaled to 80%.
