Negative Spin-Polarization Tri-Layer STO for MAMR

Layer-resolved spin polarization in Sb overlayers on NiMnSb

Negative phase advance in polarization independent, multi-layer negative-index metamaterials.

We demonstrate a polarization independent negative-index metamaterial (NIM) at microwave frequencies. Transmission measurements and simulations predict a left-handed transmission band with negative permittivity and negative permeability. A negative-index is verified by using the retrieval procedure. Effective parameters of single-layer and two-layer NIMs are shown to be different. Negative phas...

When measured spin polarization is not spin polarization.

Spin polarization is an unusually ambiguous scientific idiom and, as such, is rarely well defined. A given experimental methodology may allow one to quantify a spin polarization but only in its particular context. As one might expect, these ambiguities sometimes give rise to inappropriate interpretations when comparing the spin polarizations determined through different methods. The spin polari...

applying sto as feeder layer for rooster spermatogonial stem cell culture

the objective of this study was to evaluate the effect of the sto feeder layer on prepubertal rhode island red rooster sscs culture and proliferation in vitro. testis cells from 30 prepubertal rhode island red chicken (4-8 weeks of age), were individually separated and cultivated in the presence of  bfgf and lif growth factors on four well plates with two treatments and three replicats and five...

Polarization versus photon spin.

We examine whether the Stokes parameters of a two-mode electromagnetic field results from the superposition of the spins of the photons it contains. To this end we express any n-photon state as the result of the action on the vacuum of n creation operators generating photons which can have may different polarization states in general. We find that the macroscopic polarization holds as sum of th...
