Magnon squeezing in antiferromagnetic MnF2 and FeF2

Quantum squeezing of a collective spin-wave excitation or magnon using femtosecond optical pulses has been used to generate correlated pairs of spins with equal and opposite wave vectors in antiferromagnetic MnF2 and FeF2. In the squeezed state, the fluctuations of the magnetization of a crystallogr...
