Abstract

In this paper we report design of one virtual instrument for the measurement of resistance as a function of temperature. The program has been developed using the National Instruments’ graphical programming language ‘LabVIEW’ and has been run for the measurement of magnetoresistance of some colossal magnetoresistive (CMR) compounds, .
