The vortex morphology model of ultrasonic attenuation in the mixed state of high-Tc superconductors

This paper presents the vortex morphology model concerning the ultrasonic attenuation in the mixed state of high-Tc superconductor. This model pointed out that under different magnetic field and temperature, different vortex morphology appeared in the high-Tc superconductors. There are three factors that can determine ultrasonic attenuation, which are temperature, magnetic field and anisotropy of superconductors’ structures.
