Superconductivity of Mg–B layers prepared by a multi-energy implantation of boron into magnesium and magnesium into boron bulk substrates followed by the furnace and pulsed plasma annealing

Low Temperature STM/STS, Standard AFM and XPS οf Local MgBxPhases

“…The obtained results suggest that the simple implantation method could be useful only in case of creation of the superconducting MgB x islands rather than the smooth continuous MgB 2 thin superconducting films. To get the homogeneous MgB 2 thin film, additional steps connected with the appropriate surface thermal treatment are necessary [20]. Experiments which can test the superconductivity of MgB 2 thin film under the percolation threshold are in preparation.…”

“…In our earlier experiments thin layers of MgB x were obtained with the use of ion implantation and plasma pulse treatment method [15][16][17][18][19][20]. Samples were prepared in order to define evolution of the superconducting phases after B ions implantation into the Mg substrate or vice versa [15,16].…”

Superconductivity of MgB2Layers Prepared on Silicon Substrate by Implantation of Magnesium Ions into Boron Substrate

“…Much effort has been taken to obtain thin film of MgB 2 with a good quality and high T c and high critical current [3][4][5][6][7][8][9][10]. Our previous papers show results of the investigation of evolution of the superconducting regions in MgB 2 which forms separate islands of superconducting phase [6,[10][11][12][13][14]. We applied a few techniques: four-probe electric conductivity measurements, magnetically modulated microwave absorption (MMMA), magnetometric measurements, and the Rutherford backscattering spectroscopy (RBS).…”
