Sub 23 μHz instantaneous linewidth and frequency stability measurements of the beat note from an offset phase locked single frequency heterodyned Nd:YAG laser system

Autor: D. A. Tulchinsky

Publikováno v: Optics express. 25(20)

We report, what is to the best of our knowledge, the narrowest instantaneous linewidth measurement of the beat frequency between two phase locked heterodyned 1.319 μm Nd:YAG lasers. At both 65 kHz and 31.7 GHz beat frequencies, we measured the insta

Enhanced Spin Interactions in Digital Magnetic Heterostructures

Autor: D. A. Tulchinsky, David D. Awschalom, R. Garcia, Jeremy Levy, Nitin Samarth, Scott A. Crooker

Publikováno v: Physical Review Letters. 75:505-508

A new heterostructure is developed in which fractional monolayers of magnetic ions are introduced ``digitally'' within a semiconductor quantum well. Rearranging moments within two-dimensional (2D) planes provides additional control over their interac

Femtosecond scattering dynamics in magnetic semiconductor spin superlattices

Autor: David D. Awschalom, H. Luo, Nitin Samarth, D. A. Tulchinsky, Jacek K. Furdyna, J. F. Smyth

Publikováno v: Physical review letters. 71(4)

Spin-dependent dynamics of polarized carriers in a series of Zn 1-x Mn x Se/ZnSe superlattice structures are directly observed by time-resolved upconversion photoluminescence spectroscopy at low temperatures. Polarization measurements in small magnet

Publikováno v: Physica B: Condensed Matter. :1305-1306

Ultrafast spin dynamics in diluted magnetic semiconductor heterostructures are probed to observe the effects of dimensionally and quantum confinement on spin scattering. Two novel structures, the spin superlattice and the magnetically-coupled double
