Title: Low energy muon spin rotation and point contact tunneling on niobium thin films
Author: Tobias Junginger
Institution:
Abstract: Muon spin rotation (muSR) and point contact tunneling (PCT) are used since several years for bulk niobium studies. Here we present studies on niobium thin film samples of different deposition techniques (diode, magnetron and HIPIMS) and compare the results with RF measurements and bulk niobium results. It is consistently found from muSR and RF measurements that HIPIMS can be used to produce thin films of high RRR. Hints for magnetic impurities are found on HIPIMS and dcms samples. The Meissner effect is linear on all tested samples.
