Anisotropic thermal expansion and magnetostriction of YNi2B2C single crystals
نویسندگان
چکیده
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, inplane and along the c-axis, directions of the applied magnetic field in the intermediate superconducting state. Anisotropic uniaxial pressure dependencies of Tc were evaluated using results of zero field, thermal expansion measurements. PACS numbers: 65.40.De,74.25.Bt,74.25.Ld,74.62.Fj Submitted to: J.

متن کاملMagnetoelasticity of Fe–Si single crystals
The tetragonal magnetostriction constant, (3/2)λ100, of Fe–Si single crystals was measured and was found to be structure dependent. Similar to that of Fe–Ge single crystals, (3/2)λ100 is positive in the single phase A2 regime, becomes negative in the single phase D03 regime, and changes from positive to negative between the two regimes. Short-range order in the A2 regime decreases the magnetost...

Magnetic, linear thermal expansion (LTE), anisotropic (λt) and volume (ω) magnetostriction properties of Pr0.5Sr0.5MnO3 were investigated. The LTE decreases smoothly from 300 K without a clear anomaly either around the Curie (TC = 270 K) or the Neel temperature (TN = 100 K) and it exhibits hysteresis over a wide temperature range (60 K-270 K) upon warming. Isothermal magnetization study suggest...
