ULTRASONIC ATTENUATION IN MIXED STATE OF NIOBIUM
J. DOMINEC et K. MÍSEKInstitute of Physics of the Czechoslovak Academy of Sciences, Na Slovance 2, 180 40 Praha 8, Czechoslovakia
Abstract
We have investigated the attenuation of ultrasonic waves in
the mixed state of niobium, where a remarkable dip appears near the lower
critical field . The measurement has been performed on one sample for various
orientations of the wave vector and of the principal crystallographic axes of
the sample with respect to external magnetic field.
