Cd-doped CeCoIn5 NMR Data Under Pressure

We present nuclear magnetic resonance (NMR) data on the heavy fermion compound Cd-doped CeCoIn$_5$, in particular CeCo(In$_{1-x}$Cd$_x$)$_5$, $x=0.075$. NMR spectra for the $^{115}$In and $^{59}$Co nuclei were collected, both under pressure and at ambient pressure. The Cd doping introduces impurities which increase antiferromagnetic order and suppress superconductivity. The onset of antiferromagnetism can be seen in splitting of $^{115}$In peaks as islands of magnetic order nucleate around Cd sites.
