Abstract The new application of electron-spin resonance to paramagnetic monolayers on well characterized surfaces (LEED, AES) in UHV is described. The high sensitivity of ESR is demonstrated for 10−2 monolayers NO2 adsorbed on Xe/Ag(111), corresponding to ≈1012 detectable molecules. For monolayers of Gd(0001) on W(110) the critical exponentγ of the susceptibility and the ordering temperatureT c are determined by analysing the ESR intensity and resonance field forT→T c + . Both determinations independently give a monolayerT c of app. 271 K. The critical exponentγ changes from 2D to 3D Ising-values for monolayers to thicker films.
