THERMAL CONDUCTIVITY MEASUREMNT AT ULTRA LOW TEMPERATURES
MetadataShow full item record
Thermal Conductivity studies can provide fundamental information regarding the symmetry of the superconducting energy gap. To perform this kind of experiment, we need to use a very low temperature environment. Also a special mount has been to designed and constructed for the thermal conductivity measurements. This mount will allow holding the sample in different directions with respect to the applied magnetic field. The results are consistent with Wiedemann-Franz law to within 2.5\%. We also discuss a series of thermal conductivity experiments to shed additional light on the symmetry of the superconducting order parameter in the unconventional superconductor PrOs4Sb12.
