In the present report, we show that the dielectric properties of a charge-ordered nickelate, La15/8 Sr1/8 NiO4, surpass those of other materials. Especially, ε′ retains its colossal magnitude of >10 000 well into the gigahertz range. © 2009 American Institute of Physics.[/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]Colossal dielectric constants,Dielectric constants,Frequency ranges,Gigahertz ranges,Nickelate,Room temperatures[/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]This work was supported by the Deutsche Forschungsgemeinschaft via the Sonderforschungsbereich 484 and by the Commission of the European Communities, STREP: NUOTO, Grant No. NMP3-CT-2006-032644.
