Strong magnetic pair breaking in Mn-substituted MgB2 single crystals
Magnetic ions (Mn) were substituted in MgB2 single crystals resulting in a strong pair-breaking effect. The superconducting transition temperature, Tc, in Mg1−xMnxB2 has been found to be rapidly…
Experimental observation and simulation of unusual microwave response for the superconducting microstrip resonator at small dc magnetic field
An unusual microwave response of the surface impedance Zs of high-Tc thin films at an applied small dc magnetic field (Bdc) at 77 K, namely a decrease of Zs, is observed with the microstrip resonator…
