• current of up to 107 A/cm2. However, this critical current is only present in the MgB2 superconducting material when there is no magnetic field. The external magnetic field very rapidly suppresses the critical current and destroys the superconductivity of magnesium diboride. This issue was successfully

This

• around 20 K limits the possible use of magnesium diboride in engineering applications. Therefore, for a wide-scale technical application of MgB2 it is necessary to solve the problem of the enhancement of its critical current in an external magnetic field. Results and Discussion There have been many
