摘要：

The longitudinal ultrasonic attenuation due to spin fluctuations in anisotropic itinerant electron ferromagnets is investigated by using the self-consistent renormalization theory of spin fluctuations by Moriya and Kawabata. The anomalous attenuation at the phase boundary and the broad peak above the Curie temperature are derived, and the temperature and magnetic field dependences of the attenuation coefficient are discussed. The numerical calculations were performed using an electron gas model. © 1979, THE PHYSICAL SOCIETY OF JAPAN. All rights reserved.
