The electron spin dynamics under variable uniaxial strain is investigated in bulk cubic GaN by time-resolved magneto-optical Kerr-rotation spectroscopy. Spin relaxation is found to be approximately independent of the applied strain, in complete agreement with estimates for Dyakonov-Perel spin relaxation. Our findings clearly exclude strain-induced relaxation as an effective mechanism for spin relaxation in cubic GaN.

We used the two-component epoxy UHU plus endfest 300 from UHU GmbH, Bühl, Germany. Special care was taken in proper glueing of the samples using a homemade press device to achieve thin, uniform epoxy layers. Almost no creep or drift was observed.

Here we corrected for several misprints in the English version of the corresponding section of Ref. 25, including the correct value of γ3pop and inconsistent use of γ3.

72.

We used the values γe = 0.84 eV Å3, nDisl = 1 × 1010 cm−2 for sample A and nDisl = 2 × 109 cm−2 for sample B, respectively, as well as μpopsim=320cm2/Vs and μdislsim=120cm2/Vs for sample A and μdislsim=790cm2/Vs for sample B, respectively, for the calculation of γsD.
