NMR study of magnetic fluctuations in UTe

Tokunaga, Yo

We report our recent NMR studies on the novel spin-triplet superconductor UTe, which is at the verge of the ferromagnetic order. The upper critical field H $_{c2}$ exceeding the Pauli limit indicates the spin-triplet state. For the field along -axis, the field reentrant superconductivity is observed up to 35T, where the first order metamagnetic transition occurs. The NMR results have revealed unconventional magnetic and superconducting properties of this compound from a microscopic point of view.
