摘要：

Phonon-exchange pumping of nuclear magnon pairs in low-anisotropy flopped antiferromagnets is proposed and the effective threshold fields given. Although the electronic sublattice magnetizations are driven, magnetoelastically, far below their resonance frequency, the lower pump frequency compensates for the weakened dynamic coupling between nuclear and electronic magnons. The required phonon power density is thus low and well within experimental reach. © 1969 The American Physical Society.
