✦ Synopsis

Recent transmission electron microscopy (TEM) data on the heavy fermion superconductor UPt3 find a complex periodic modulation in the basal plane, the nature of which is unclear. We present TEM data on single crystal whiskers of UPt3 grown spontaneously from the melt. We find a modulation in the a-c plane, consistent with a description in terms of a single q, allowing us to present the first accurate determination of the c* component of the modulation. This structure persists across a wide area of the whisker, making these samples candidates for X-ray studies of the modulation.
