Thermal Expansion and Magnetostriction Measurements at Cryogenic Temperature Using the Strain Gauge Method
Thermal expansion and magnetostriction, the strain responses of a material to temperature and a magnetic field, especially properties at low temperature, are extremely useful to study electronic and phononic properties, phase transitions, quantum criticality, and other interesting phenomena in cryogenic engineering and materials science. However, traditional dilatometers cannot provide magnetic...
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 کاملCapacitance Bridge Measurements of Magnetostriction for Engineering Applications of Magnetoelastic Materials
Recently developed magneto-elastic torquesensing technology usually employs circumferentially magnetized shafts or rings of specially formulated alloy steels that have undergone unique processing treatments to enhance their efficiency. Identifying these suitable alloys and assuring their appropriate sensor performance has proven to be an expensive and tedious process. In order to promote the wi...
متن کاملCapacitive-based dilatometer cell constructed of fused quartz for measuring the thermal expansion of solids.
A dilatometer cell that can detect sub angstrom changes in the length of solid specimens in the temperature range 5 K<T<350 K is described. It is constructed entirely from fused quartz (silica). This is a capacitive-based technique, where the spacing between two metallized plates allows detection of changes in length. It is also a relative measurement in the sense that the capacitor plate spaci...
متن کاملThermal expansion and magnetostriction of pure and doped RAgSb(2) (R = Y, Sm, La) single crystals.
Data on temperature-dependent, anisotropic thermal expansion in pure and doped RAgSb(2) (R = Y, Sm, La) single crystals are presented. Using the Ehrenfest relation and heat capacity measurements, uniaxial pressure derivatives for long range magnetic ordering and charge density wave transition temperatures are evaluated and compared with the results of the direct measurements under hydrostatic p...
