Two-Pulse and Stimulated Echoes in Yttrium and Bismuth Based HTS C Powders
並列摘要
Experimental data on a two-pulse and a stimulated echoes in a superconducting YBaCuO and BiSrCaCuO powders in a static magnetic field at a frequency～20 MHz' are presented. The field, filling helium gas pressure and temperature dependence of the echo intensity and relaxation time were measured. A stimulated echo has been even detected some hours after the removal of exciting pulses (the memory effect). The echoes are practically disappeared at temperatures 50 K for yttrium powder and at 30 K in the case of Bi-powder. Experimental results are in a qualitative agreement with a supposition that the phase coherence arises due to the movement of lattice imperfections by vortex lines.
