Self-Assembled Multiferroic Nanostructures in CoFe 2 O 4- PbTiO 3 System

October 12, 2021
Author(s)
Jiying Li, Igor Levin, Julia Slutsker, Virgil Provenzano, Peter K. Schenck, J.H. Yang, Alexander L. Roytburd
The effect of substrate orientation of the morphologies of epitaxial self-assembled nanostructures was demonstrated using newly synthesized multiferroic 0.67PbTiO3-0.33CoFe2O4 nanocomposite thin films. The two-phase nanostructures were grown on single

Helical Magnetic Order in MnSi Thin Films

… normal. The spin wave stiffness is found to drop from A= 0.67 meV nm 2 to 0.50 meV nm 2 as the thickness increases from 11 nm to 40nm. The helix wavelength of 2π/Q = 13.9 + or-}nm that is independent of thickness is explained by a …

Measurement of the self-broadening rate coefficients of the cesium resonance lines

November 1, 1995
Author(s)
Zeina J. Kubarych, J Huennekens, R K. Namiotka, J Sagle
The self-broadening rate coefficients of the cesium D1 [62S1/2 - 62P1/2] and D2 [62S1/2 - 62P3/2] resonance lines are determined from the 62P1/2 --> 62D3/2, 62D3/2---> 72D3/2 and 62P3/2 --> 72D5/2 transition lineshapes, which are mapped out using single

Compact and Tunable Forward Coupler Based on High-Impedance Superconducting Nanowires

February 25, 2021
Author(s)
Marco Colangelo, Di Zhu, Daniel F. Santavicca, Brenden Butters, Joshua Bienfang, Karl K. Berggren
Developing compact, low-dissipation, cryogenic-compatible microwave electronics is essential for scaling up low-temperature quantum computing systems. In this paper, we demonstrate an ultracompact microwave directional forward coupler based on high

Quamtum coherence between two atoms beyond Q=10 15

April 22, 2011
Author(s)
Chin-Wen Chou, David Hume, Michael J. Thorpe, David J. Wineland, Till P. Rosenband
We place two atoms in quantum superposition states and observe coherent phase evolution for 3.4 × 10 15 cycles. Correlation signals from the two atoms yield information about their relative phase even after the probe radiation has decohered. This technique
