Nanovoids in As2S3-based glasses (As 2S3, (As2S3)85Ag 15, and (As2S3)85(AgI) 15), a polymer and a As2S3-polymer nanocomposite were studied using the positron annihilation lifetime spectroscopy (PALS) technique. After ...

In the present work the magnetic properties of Ag/AgI-As2S3 glasses are studied using magnetic susceptibility (MS) measurement by the Faraday method at the temperatures of 293 and 77 K. On the basis of the MS experimental ...
