“…The discovery of superconductivity in magnesium diboride (MgB 2 ) at 39 K [1] has attracted worldwide interest for both fundamental physical study and application [2,3]. The relatively high critical temperature, the low cost and the 'weak-link' free grain boundaries make MgB 2 an excellent candidate for the fabrication of wires and tapes [4].…”

“…The adiabatic critical state model, which was developed by Swartz and Bean, explains the flux jump phenomenon as a adiabatic process Fig. 5 Field dependence of the magnetic moment for the MgB 2 bulk sample at 10 K [19][20][21][22]. The adiabatic critical state model was based on the fact that flux jump occurs in the state at which the diffusivity of the magnetic flux is faster than the thermal diffusivity.…”

MgB 2 samples were prepared from a stoichiometry mixture of Mg and B inside stainless steel tubes. The transition temperature of the specimens was 37.5 K with a sharp transition width within 1 K. From the magnetic hysteresis measurements, flux jump was observed up to 15 K. The flux jump is believed to begin at the fluxes pinned at the defects. An over-moving flux situation formed at the places where there were moving fluxes that had been pinned at the defect and steady state ones. The flux jumps depend not on the amount of impurities and second phases, but on their distribution, pinning strength and heat capacity.

“…This is the result of the flux pinning effects by the FeTi particles in MgB 2 . The adiabatic critical state model, which was developed by Swartz and Bean, explains the flux jump phenomenon as a adiabatic process [13][14][15][16]. The adiabatic critical state model was based on the fact that flux jump occurs in the state at which the diffusivity of the magnetic flux is faster than the thermal diffusivity.…”
