Quantum Mechanics of Spin Transfer in Ferromagnetic Multilayers
Wonkee Kim, F. Marsiglio
We use a quantum mechanical treatment of a ballistic spin current to describe novel aspects of spin transfer to a ferromagnetic multilayer. We demonstrate quantum phenomena from sp…
Dynamics of a magnetic moment induced by a spin-polarized current
Wonkee Kim, F. Marsiglio
Effects of an incoming spin-polarized current on a magnetic moment are explored. We found that the spin torque occurs only when the incoming spin changes as a function of time insi…
Low Temperature Thermal Conductivity of High Purity YBaCuO in the Vortex State
Wonkee Kim, F. Marsiglio, J. P. Carbotte
The low temperature thermal conductivity of a d-wave superconductor is considered for arbitrary strength of the impurity potential. A random distribution of vortices is included wi…
Superconductivity in Ba_2Sn_3Sb_6 and SrSn_3Sb_4
Laura Deakin, Robert Lam, Frank Marsiglio +1
Resistivity and ac magnetic susceptibility measurements on Ba2Sn3Sb6 and SrSn3Sb4 indicate that these Zintl compounds display a transition to a superconducting phase at Tc = 3.9 K.…
Inversion of ARPES measurements in high Tc cuprates
S. Verga, A. Knigavko, F. Marsiglio
Recent energy dispersion measurements in several families of the hole-doped copper oxides have revealed a kink in the energy vs. momentum relation. These have tentatively been iden…
Expansion in the "distance" from Hc2(T) line for the mixed state of BCS superconductors
Anton Knigavko, Frank Marsiglio
We develop a description of the mixed state of type II superconductivity valid within a wide range of temperatures and external magnetic fields. It is based on the quasiclassical v…
