Field-induced compensation of magnetic exchange as the possible origin of reentrant superconductivity in UTe2

We investigated several micron-sized samples produced from one oriented single crystal with a superconducting T_c of 1.6 K. The micromachining was performed by means of Ga or Xe FIB systems (for details, see the methods section). This FIB approach enables precise geometries suitable for microcantilever-torque experiments on magnetic materials with strong torque responses as well as high-precision electrical-transport measurements on metallic (i.e., highly conductive) materials with current running along any desired direction (see images in Fig. 1a, b). In this work, we will present…
