The two-dimensional quantum ferromagnet filled with a liquid of skyrmi
ons is studied theoretically in the context of the quantum Hall effect
near electronic filling factor nu = 1. A crossover between the classi
cal ferromagnetic phase at nu = 1 and a classical paramagnetic phase a
t nu not equal 1 is obtained, which is consistent with recent Knight-s
hift measurements. A new collective mode associated with the skyrmion
liquid that is of the cyclotron type is also identified.
