Abstract
We present specific-heat C measurements of a high-quality polycrystal of UBe13 for 0.2≤T≤1.2 K and 0≤H≤80 kG. Field-sweep data, C(H) at fixed T, reveal two broad peaks in the superconducting state for T<0.6 K. The low-field feature occurs at H≊20 kG, independent of temperature. Conventional temperature scans, C(T) at fixed H, presumably smear this feature beyond recognition.
