It was found that the data analyzed following the Hao-Clem model exhibit an excellent fit to the theoretical curve for Hc(T) derived from the BCS model over the relatively broad temperature range from 11.25 K to 19 K (slightly below the critical temperature of 21 K). The result of the analysis yields a constant κ̄ value of 80 over the temperature range considered. Additional parameters determined in this experiment include Hc2(0) = (9.0 ± 0.8) × 105 Oe, ξab(0)=(19.14 ± 1.67)Å with λab(0) = (1493 ± 131) Å in the dirty limit and Hc2(0) = (6.7 ± 0.6) × 105 Oe, ξab(0)=(22.22 ± 1.94)Å with λab(0) = (1733 ± 152)Å in the clean limit. It is further established from this experiment that the Hao-Clem model is particularly suited for the study of reversible magnetization of low-Tc superconductors with relatively subdued anisotropy such as the sample considered in this study. © 1999 American Physical Society.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1103/PhysRevB.60.15384[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
