Structure, superconductivity and magnetic properties of mechanically alloyed Mg1=xFexB2 powders with x = 0-0.4

Mechanical milling of Mg1-xFexB2 with x = 0-0.4 led to the formation of amorphous phase. For x = 0, the hexagonal MgB2 phase was formed after a heat treatment at 450DGC or above with critical temperature Tc = 38-40 K. Fe-substituted MgB2 phase was formed after annealing at 450DGC or above when x = 0...
