Hydrostatic and uniaxial pressure dependence of superconducting transition temperature of KFe2As2 single crystals
We present heat capacity, c-axis thermal expansion and pressure-dependent, low-field, temperature-dependent magnetization for pressures up to ∼12 kbar, data for KFe2As2 single crystals. Tc decreases under pressure with dTc/dP≈−0.10 K/kbar. The inferred uniaxial, c-axis, pressure derivative is positive, dTc/dpc≈0.11 K/kbar. The data are analyzed in comparison with those for overdoped Fe-based su...
متن کاملAn FBG Optical Approach to Thermal Expansion Measurements under Hydrostatic Pressure
We report on an optical technique for measuring thermal expansion and magnetostriction at cryogenic temperatures and under applied hydrostatic pressures of 2.0 GPa. Optical fiber Bragg gratings inside a clamp-type pressure chamber are used to measure the strain in a millimeter-sized sample of CeRhIn₅. We describe the simultaneous measurement of two Bragg gratings in a single optical fiber using...
متن کاملAnisotropic thermal expansion and magnetostriction of YNi2B2C single crystals
We present results of anisotropic thermal expansion and low temperature magnetostriction measurements on YNi2B2C single crystals grown by high temperature flux and floating zone techniques. Quantum oscillations of magnetostriction were observed at low temperatures for H‖c starting at fields significantly below Hc2 (H < 0.7Hc2). Large irreversible, longitudinal magnetostriction was seen in both,...
متن کاملAnisotropic thermal expansion and uniaxial pressure dependence of superconducting and magnetic transitions in ErNi2B2C
We present anisotropic thermal expansion measurements on single crystalline ErNi2B2C. All three, superconducting, antiferromagnetic and weak ferromagnetic phase transitions are unambiguously distinguished in the data. Anisotropic uniaxial pressure dependencies of the transitions are estimated based on the Ehrenfest relation, leading to a conclusion, in particular, that weak ferromagnetic state ...
متن کاملHigh-resolution thermal expansion measurements under helium-gas pressure.
We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4 K ≤ T ≤ 300 K and hydrostatic pressure P ≤ 250 MPa. Helium ((4)He) is used as a pressure-transmitting medium, ensuring hydrostatic-pressure conditions. Special emphasis has been given to guarantee, to a good approximation, constant-pressure con...
