a \({T}_{2}^{{{{{{{{\rm{E}}}}}}}}}\) spin echo measurements on samples S1 (h10B15N) and S4 (hBNnat). Insets: \({T}_{2}^{{{{{{{{\rm{XY}}}}}}}}}\) XY8 measurements on samples S1 and S4. Error bars represent 1 s.d. accounting statistical uncertainties. b Bottom: extracted spin coherence timescales \({T}_{2}^{{{{{{{{\rm{E}}}}}}}}}\) and \({T}_{2}^{{{{{{{{\rm{XY}}}}}}}}}\). Top: extracted spin relaxation timescales T1 for all six hBN samples investigated in this work. Error bars in time represent 1 s.d. accounting fitting error. c Relaxation timescales T1 for both h10B15N and hBNnat under different temperatures. Inset: T1 measurement comparison with temperature at 10 K. Error bars represent 1 s.d. accounting statistical uncertainties, and error bars in T1 represent 1 s.d. accounting fitting error.
