To determine the relaxation mechanisms at stake, measurements of the T1 relaxation time are performed for a set of individual NV centers both at room and cryogenic temperatures. The results are consistant with a temperature-dependent relaxation process, which is attributed to a thermally activated magnetic noise produced by paramagnetic impurities lying on the nanodiamond surface. These results confirm the existence of surface-induced spin relaxation processes occurring in nanodiamonds, which are relevant for future developments of sensitive nanoscale NV-based quantum sensors. %G English %2 https://hal.science/hal-03001778/document %2 https://hal.science/hal-03001778/file/PhysRevB.102.165427.pdf %L hal-03001778 %U https://hal.science/hal-03001778 %~ CNRS %~ ENS-CACHAN %~ L2C %~ CENTRALESUPELEC %~ UNIV-PARIS-SACLAY %~ MIPS %~ UNIV-MONTPELLIER %~ TEST-HALCNRS %~ LUMIN %~ LUMIN-LUMIERE-MATIERE %~ UNIVERSITE-PARIS-SACLAY %~ ENS-PARIS-SACLAY %~ ENS-PSACLAY %~ GS-ENGINEERING %~ GS-PHYSIQUE %~ GS-LIFE-SCIENCES-HEALTH %~ INSTITUT-SCIENCES-LUMIERE %~ UM-2015-2021
