Magnetoelectronic spin echo.

چکیده
We predict a spin echo in electron transport through layered ferromagnetic-normal-ferromagnetic metal structures: whereas a spin current polarized perpendicular to the magnetization direction decays when traversing a single homogeneous ferromagnet on the scale of the ferromagnetic spin-coherence length, it partially reappears by adding a second identical but antiparallel ferromagnet. This reentrant transverse spin current resembles the spin-echo effect in the magnetization of nuclei under pulsed excitations. We propose an experimental setup to measure the spin echo.

Thermal spin-transfer torque in magnetoelectronic devices.
We predict that the magnetization direction of a ferromagnet can be reversed by the spin-transfer torque accompanying spin-polarized thermoelectric heat currents. We illustrate the concept by applying a finite-element theory of thermoelectric transport in disordered magnetoelectronic circuits and devices to metallic spin valves. When thermalization is not complete, a spin heat accumulation vect...
متن کاملPerpendicular spin valves with ultrathin ferromagnetic layers: Magnetoelectronic circuit investigation of finite-size effects
We address two finite-size effects in perpendicular transport through multilayers of ferromagnetic and normal metal layers: i the transport properties depend on the magnetic layer thickness when of the order or thinner than the spin-flip diffusion length and ii magnetic layers with thickness approaching the magnetic coherence length become transparent for spin currents polarized perpendicular t...

Introduction: Non-uniformity is one of the most important parameters affecting MRI images which can lead to harmful effects in the diagnosis and analysis of qualitative and quantitative methods. The present study introduced a method for measuring RF non-homogeneity in MRI systems. Methods and Materials: To verify the uniformity of B0 and B1 fields, a cylindrical phantom with a diameter of 24 c...
متن کاملAssessment of the Characteristics of MRI Coils in Terms of RF Non-Homogeneity Using Routine Spin Echo Sequences
Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of non-homogeneity in RF receive and transmit. This can be the most effective source of error in quantitative studies in MRI imaging. Part of this non-homogeneity demonstrates the characteristics of RF coil and part of it is due to the interaction of RF field with the material being imaged...
متن کاملMagnetization noise in magnetoelectronic nanostructures.
By scattering theory we show that spin current noise in normal electric conductors in contact with nanoscale ferromagnets increases the magnetization noise by means of a fluctuating spin-transfer torque. Johnson-Nyquist noise in the spin current is related to the increased Gilbert damping due to spin pumping, in accordance with the fluctuation-dissipation theorem. Spin current shot noise in the...
