Abstract
Sound attenuation and velocity in nickel single crystals have been studied as function of frequency (10 to 250 MHz), temperature, strength and direction of external magnetic field along <111>, <110> and <100>, for the three pure wave modes propagating along <100>. The observed effects are found to be specific for each combination of sound mode and field direction, and especially interesting for the field along <100> which is the hard magnetization direction in Ni. The measured frequency, field, and temperature effects on sound attenuation and velocity can be rationalized in terms of field induced changes of the domain structure.
