Here, the generalized Bloch–Gruneisen (BG) function is described with wide range of temperatures in addition with some other parameters. This function shows the easy and precise method to determine the resistivity as a function of temperature for pristine nano-MgB2 sample. The fitted outcomes are in resemblance with the experimental results up to 20–150 K temperature range. This generalized BG function is appropriate for diverse non-integers and integers values of n. Experimental result is full agreement with the fitted data for n = 4 integer value. Furthermore, the present method exposes the accuracy, easiness and preciseness of the results up to a high order of decimals for the determination of the resistivity as a function of temperature. |
