The irreversibility temperatures {ital T}{sub {ital r}}({ital H}) for the {ital c}-axis-oriented powders of pure and alloyed YBa{sub 2}Cu{sub 3}O{sub 7},Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}, and Bi{sub 2}Sr{sub 2}Ca{sub 2}O{sub 10} were measured for {bold c}{parallel}{bold H}. The results suggest that these temperatures are not the theoretically predicted vortex-lattice melting temperatures nor the vortex-glass-to-liquid transition temperatures.
