Highly selective detection of individual nuclear spins with rotary echo on an electron spin probe
We consider an electronic spin, such as a nitrogen-vacancy center in diamond, weakly coupled to a large number of nuclear spins, and subjected to the Rabi driving with a periodically alternating phase. We show that by switching the driving phase synchronously with the precession of a given nuclear spin, the interaction to this spin is selectively enhanced, while the rest of the bath remains dec...
متن کاملNuclear modulation effects in ‘‘211’’ electron spin-echo correlation spectroscopy
This work represents the synthesis of the 211 pulse sequence for the study of electron spin-echo envelope modulation ~ESEEM! with the technique of spin-echo correlated spectroscopy ~SECSY!, which has previously been used to study nuclear modulation by two-dimensional Fourier transform ESR methods. This example of ‘‘pulse adjustable’’ spectroscopy, wherein the pulse width and pulse amplitude of ...
متن کامل5- and 6-pulse electron spin echo envelope modulation (ESEEM) of multi-nuclear spin systems.
In 3-pulse ESEEM and the original 4-pulse HYSCORE, nuclei with large modulation depth (k approximately 1) suppress spectral peaks from nuclei with weak modulations (k approximately 0). This cross suppression can impede the detection of the latter nuclei, which are often the ones of interest. We show that two extended pulse sequences, 5-pulse ESEEM and 6-pulse HYSCORE, can be used as experimenta...
متن کاملElectrical spin injection and detection in lateral all-semiconductor devices
Both electrical injection and detection of spin-polarized electrons are demonstrated in a single wafer allsemiconductor GaAs-based lateral spintronic device, employing p+Ga,Mn As /n+-GaAs ferromagnetic Esaki diodes as spin aligning contacts. Spin-dependent phenomena, such as spin precession and spin-valve effect, are observed in nonlocal signal and the measurements reveal the unusual origin of ...
متن کاملElectrical spin injection and detection in molybdenum disulfide multilayer channel
Molybdenum disulfide has recently emerged as a promising two-dimensional semiconducting material for nano-electronic, opto-electronic and spintronic applications. However, the demonstration of an electron spin transport through a semiconducting MoS2 channel remains challenging. Here we show the evidence of the electrical spin injection and detection in the conduction band of a multilayer MoS2 s...
