However, establishing quantitative correlations between the hydrogen content and the physical properties of solids remains a formidable challenge. Here we report neutron reflectometry experiments on 50 nm thick niobium films during hydrogen loading, and show that the momentum-space position of a prominent waveguide resonance allows tracking of the absolute hydrogen content with an accuracy of about one atomic percent on a timescale of less than a minute. Resonance-enhanced neutron reflectometry thus allows fast, direct, and non-destructive measurements of the hydrogen concentration in thin-film structures, with sensitivity high enough for real-time in-situ studies.}, cin = {JCNS-4 / MLZ}, ddc = {500}, cid = {I:(DE-Juel1)JCNS-4-20201012 / I:(DE-588b)4597118-3}, pnm = {6G4 - Jülich Centre for Neutron Research (JCNS) (FZJ) (POF4-6G4) / 622 - Detector Technologies and Systems (POF4-622)}, pid = {G:(DE-HGF)POF4-6G4 / G:(DE-HGF)POF4-622}, experiment = {EXP:(DE-MLZ)MBE-MLZ-20151210 / EXP:(DE-MLZ)N-REX-20140101}, typ = {PUB:(DE-HGF)16}, pubmed = {35304444}, UT = {WOS:000770716000011}, doi = {10.1038/s41467-022-29092-z}, url = {https://juser.fz-juelich.de/record/907713}, }
