Lattice-based optical clock using an even isotope of Yb

September 12, 2007
Author(s)
Zeb Barber, C Hoyt, Jason Stalnaker, Nathan D. Lemke, Christopher W. Oates, Tara M. Fortier, Scott A. Diddams, Leo W. Hollberg
We describe progress toward an optical lattice clock based on an even isotope of Yb. The 1S_0 - P_0 clock resonance in 174Yb is accessed using a magnetically induced spectroscopic technique. Using ~1 mT static magnetic fields and ~10 uW of probe light

Boltzmann Test of Slonczewski's Theory of Spin Transfer Torque

November 12, 2004
Author(s)
J Xiao, A Zangwill, Mark D. Stiles
We use a matrix Boltzmann equation formalism to test the accuracy of Slonczewski's theory of spin-transfer torque in thin-film heterostructures where a non-magnetic spacer layer separates two non-collinear ferromagnetic layers connected to non-magnetic

Variable-temperature critical-current measurements on a Nb-Ti wire

July 27, 2004
Author(s)
Loren F. Goodrich, Theodore C. Stauffer
We made variable-temperature critical-current (I c) measurements on a commercial multifilamentary Nb-Ti wire for temperatures (T) from 4 to 9 K and magnetic fields (H) from 0 to 11.5 T using transport current. The measurements cover the whole range of

The superconducting strand for the CMS solenoid conductor

… at CERN. The design filed of the CMS superconducting magnet is 4 T, the magnetic length is 12.5 m and the free …

Exchange Bias Relaxation in CoO-Biased Films

May 1, 2000
Author(s)
Robert McMichael, Chang H. Lee, Mark D. Stiles, F Serpa, P J. Chen, William F. Egelhoff Jr.
Because the memory of the bias direction is carried by the antiferromagnetic order in exchange bias films, the stability of the antiferromagnetic order is critical to the existence of the exchange bias field. Ferromagnetic resonance was used to measure the
