Magnetic rare-earth (RE) borocarbide superconductors (RE-Ni2B2C) exhibit a wide variety of phenomena due to the interplay between their superconducting and magnetic properties. Recently, high quality thin films of the 'non-magnetic' compound YNi2B2C were successfully obtained. in the present report, the 'in-situ' deposition of ErNi2B2C thin films by planar magnetron sputtering is presented together with a comprehensive set of characterizations, including d.c. resistivity, critical current, magnetization, critical fields and quasiparticle density of states by low temperature scanning tunnel microscope (STM). Experimental data are compared with currently available results on single crystals.

Abstract
Magnetic rare-earth (RE) borocarbide superconductors (RE-Ni2B2C) exhibit a wide variety of phenomena due to the interplay between their superconducting and magnetic properties. Recently, high quality thin films of the 'non-magnetic' compound YNi2B2C were successfully obtained. in the present report, the 'in-situ' deposition of ErNi2B2C thin films by planar magnetron sputtering is presented together with a comprehensive set of characterizations, including d.c. resistivity, critical current, magnetization, critical fields and quasiparticle density of states by low temperature scanning tunnel microscope (STM). Experimental data are compared with currently available results on single crystals.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
