 Spin-valley locking leads to large critical magnetic fields.
 A similar phenomena was recently reported in heavily hole-doped
 (beyond the spin-split gap) \ce{NbSe2}

 In the new regime, where only one band per valley intersects
 the chemical potential, no pair-breaking occurs
 for in-plane fields unless disorder is present.
