Computational Study of Field-Dependent Pinning Force for Pure MgB2 Superconductor.

The logarithmic exponential regression model is proposed for the pure MgB₂ superconductor in this study. The predicted values of normalized pinning force as a function of the reduced field are evaluated and compared to the measured values at a wide range of temperatures. The proposed model well described the best-suited model for the estimated predicted values. The predicted values of the reduced field dependence of normalized pinning force are in good agreement with the measured values for the pure MgB₂ superconductor. Some statistical error estimations namely mean bias error, mean absolute bias error and root mean square error is calculated at different temperatures from 10-30K. The large value of the coefficient of regression, R² confirms the effectiveness and significance of the proposed model. The proposed model is applicable in this study to find the accurate and precise values of the computational data. [ABSTRACT FROM AUTHOR]
