Query: Controlling superconductivity of CeIrIn$_5$ microstructures by substrate
  selection   Superconductor/metal interfaces are usually fabricated in heterostructures
that join these dissimilar materials. A conceptually different approach has
recently exploited the strain sensitivity of heavy-fermion superconductors,
selectively transforming regions of the crystal into the metallic state by
strain gradients. The strain is generated by differential thermal contraction
between the sample and the substrate. Here, we present an improved
finite-element model that reliably predicts the superconducting transition
temperature in CeIrIn$_5$ even in complex structures. Different substrates are
employed to tailor the strain field into the desired shapes. Using this
approach, both highly complex and strained as well as strain-free
microstructures are fabricated to validate the model. This enables full control
over the microscopic strain fields, and forms the basis for more advanced
structuring of superconductors as in Josephson junctions.
