The　microstructure,　crystal　structure,　and　magnetic　properties　were　studied　for　(Nd,　Tb)(2)Fe14B　nanoflakes　prepared　by　surfactant-assisted　high-energy　ball　milling　(HEBM).　Effects　of　ball-milling　time　on　the　c-axis　crystallographic　alignment,　morphology,　and　magnetic　properties　of　(Nd,　Tb)(2)Fe14B　nanoflakes　were　systematically　investigated.　X-ray　diffraction　(XRD)　results　indicate　that　the　average　crystal　grain　size　of　the　nanoflakes　decreases　from　60　nm　of　1　hour　milling　to　33　nm　of　7　hours　milling.　The　nanoflakes　milled　for　3　hours　bear　an　average　thickness　of　100　nm　and　an　average　diameter　of　2　mu　m　leading　to　a　high　aspect　ratio　of　20.　In　addition,　the　intensity　ratio　of　I-(006)/I-(105)　indicates　that　the　degree　of　c-axis　crystal　texture　increases　first,　peaks　for　3　hours,　then　drops　with　increasing　the　milling　time.　Meanwhile,　the　coercivity　(Hc)　of　the　nanoflakes　drops　monotonically.　The　remanence　(Mr)　of　nanoflakes　milled　for　3　hours　in　the　easy　axis　direction　is　11　kG,　while　the　Mr　in　the　hard　axis　direction　is　1.8　kG,　indicating　a　strong　magnetic　anisotropy.　The　optimal　magnetic　properties　of　Mr　of　11　kG,　and　Hc　of　7　kOe,　(BH)　max　of　24.7　MGOe　have　been　achieved.　(C)　2017　Author(s).
