Abstract
A phenomenon of controlled self-modulation of ultrasonic pulses passed through a magnetized magnetic liquid is experimentally found. It is supposed that the observed phenomenon is determined by the formation of a specific structure of ferroparticles under a long-term influence of a magnetic field.
