| Abstract: | The 1 K phase transition in UCu5, which shows up in specific heat data within the antiferromagnetic state belowT N =16 K, was investigated by zero field μSR. The data reveal a pronounced increase in the internal field spread at theμ + sites below 1.2 K while the average fields seem to be unaffected. These results are compatible with the onset of a charge density wave state below 1.2 K. |
