Phosphorus Spin Coherence Times in Silicon at Very Low Temperatures
L. K. Alexander, N. Suwuntanasarn, W. D. Hutchison
Phosphorus donor spin coherence in isotopically pure 28 silicon is measured at very low temperatures using pulsed electron spin resonance. The isolated spin T2 varies unexpectedly…
Pulsed ESR Measurement of Coherence Times in Si:P at Very Low Temperatures
W. D. Hutchison, L. K. Alexander, N. Suwuntanasarn +1
A purpose built millikelvin pulsed x-band ESR system is used to measure spin decoherence times of phosphorus donor spins in 99.92% isotopically pure 28 silicon. The isolated P spin…
ESR studies of ion implanted phosphorus donors near the Si-SiO2 interface
Paul G. Spizzirri, Wayne D. Hutchison, Nikolas Stavrias +4
This work reports an ESR study of low energy, low fluence phosphorus ion implantation into silicon in order to observe the activation of phosphorus donors placed in close proximity…
Impurity effects in coupled-ladder BiCu2PO6 studied by NMR and quantum Monte Carlo simulations
L. K. Alexander, J. Bobroff, A. V. Mahajan +3
We present a 31P NMR study of the coupled spin 1/2 ladder compound BiCu2PO6. In the pure material, intrinsic susceptibility and dynamics show a spin gap of about . Substitution of…
Doping effects in the coupled, two-leg spin ladder BiCu2PO6
B. Koteswararao, A. V. Mahajan, L. K. Alexander +1
We report preparation, x-ray diffraction, magnetic susceptibility chi(T) and heat capacity Cp(T) measurements on the undoped samples as also samples with Zn-doped (S = 0) at Cu sit…
Supplementary material for "Impurity-induced magnetic order in low dimensional spin gapped materials"
J. Bobroff, N. Laflorencie, L. K. Alexander +3
In this supplementary material, we investigate further the impurity-induced freezing mechanism in a doped system of 3D weakly coupled ladders resembling Bi(CuZn)ZnP…
