Strong pinning and slow flux creep relaxation in Co-doped CaFe2As2 single crystals
(Pergamon-Elsevier Science Ltd, 2020-09)
We report on measurements of critical current densities Jc and flux creep rates S of freestanding Ca(Fe1−xCox)2As2 (x ≈ 0.033) single crystals with Tc ≈ 15.7 K by performing magnetization measurements. The magnetic field ...
Study of KCl + x% in and KCl + y% TlCl thin films
(1998-12-01)
The present work reports the study of KCl thin films doped with In+ or Tl+. Both systems show optical absorption bands similar to single crystals. As the impurity concentration increases, so does the absorption as also the ...

Absorption and fluorescence of Er3+-doped LiYF4: Measurements and simulation
(1998-07-24)
Er3+:LiYF4 single crystal has been studied by absorption and fluorescence spectroscopy in the IR-visible-UV (0-44000 cm-1) region from 4.2 K to room temperature. Polarized spectra were recorded in order to assign numerous ...
