“…Compressive uniaxial stress or strain can, for example, be experimentally realized by fixing a sample between two anvils. [95,96] Conversely, tensile stress or strain can be achieved by pulling on two ends of a sample, [97,98] for example, in so-called "quartz puller" [97] or "horseshoe" devices. [38] More recent technical developments involve the use of piezoelectric actuators, [37,79,80,[99][100][101] which can be conveniently, controllably and continuously strained by the application of an external voltage and therefore allow a control of uniaxial strain or stress of samples in situ at low temperatures.…”

Iron-based superconductors are well-known for their intriguing phase diagrams, which manifest a complex interplay of electronic, magnetic, and structural degrees of freedom. Among the phase transitions observed are superconducting, magnetic, and several types of structural transitions, including a tetragonal-to-orthorhombic and a collapsed-tetragonal transition. In particular, the widely observed tetragonal-to-orthorhombic transition is believed to be a result of an electronic order that is coupled to the crystalline lattice and is, thus, referred to as nematic transition. Nematicity is therefore a prominent feature of these materials, which signals the importance of the coupling of electronic and lattice properties. Correspondingly, these systems are particularly susceptible to tuning via pressure (hydrostatic, uniaxial, or some combination). Efforts to probe the phase diagrams of pressure-tuned iron-based superconductors are reviewed with a strong focus on recent insights into the phase diagrams of several members of this material class under hydrostatic pressure. These studies on FeSe, Ba(Fe 1−x Co x) 2 As 2 , Ca(Fe 1−x Co x) 2 As 2 , and CaK(Fe 1−x Ni x) 4 As 4 are, to a significant extent, made possible by advances of what measurements can be adapted to their use under differing pressure environments. The potential impact of these tools for the study of the wider class of strongly correlated electron systems is pointed out.

Other examples are the use of strain to modify transition temperatures and tune through the phase diagram in systems with superconducting (2,3,5), magnetic (6), or ferroquadrupolar order (11). One of the main advantages of using strain is that it provides control over the symmetry of the elastic deformation and can therefore selectively probe the elastic response along certain crystallographic directions, induce a desired symmetry change of the electronic and lattice structure, or couple to particular electronic orders and their fluctuations (7,10,11).…”

Strain describes the deformation of a material as a result of applied stress. It has been widely employed to probe transport properties of materials, ranging from semiconductors to correlated materials. In order to understand, and eventually control, transport behavior under strain, it is important to quantify the effects of strain on the electronic bandstructure, carrier density, and mobility. Here, we demonstrate that much information can be obtained by exploring magnetoelastoresistance (MER), which refers to magnetic field-driven changes of the elastoresistance. We use this powerful approach to study the combined effect of strain and magnetic fields on the semimetallic transition metal dichalcogenideWTe2. We discover that WTe2shows a large and temperature-nonmonotonic elastoresistance, driven by uniaxial stress, that can be tuned by magnetic field. Using first-principle and analytical low-energy model calculations, we provide a semiquantitative understanding of our experimental observations. We show that inWTe2, the strain-induced change of the carrier density dominates the observed elastoresistance. In addition, the change of the mobilities can be directly accessed by using MER. Our analysis also reveals the importance of a heavy-hole band near the Fermi level on the elastoresistance at intermediate temperatures. Systematic understanding of strain effects in single crystals of correlated materials is important for future applications, such as strain tuning of bulk phases and fabrication of devices controlled by strain.
