| Abstract Scope |
This research outlines the measurement of the residual resistivity ratio(RRR) of niobium(Nb) and Tantalum(Ta). RRR is an important property related to sample purity and superconductivity, yet experimental RRR data are not available for Nb at superconducting temperatures. Using the four-point probe method and cryogenic cycling techniques, it is possible to obtain the resistivities of the target materials across a broader range than what is currently available. Expanded RRR information of Nb will aid in implementing the use of Nb in the design of engineered systems such as space electronic devices. The collinear four-point probe method is used to acquire resistivities of the testing samples across a range of 4-300 kelvin. A preliminary comparative study with Ta property data from the National Institute of Standards and Technology (NIST) is used to verify accurate results due to its similar chemical properties to Nb. |
