abstract = {We report discovery of KFe1.05Ag0.88Te2 single crystals
with semiconducting spin glass ground state. Composition and
structure analyses suggest nearly stoichiometric I4/mmm
space group but allow for the existence of vacancies, absent
in long-range semiconducting antiferromagnet
KFe0.85Ag1.15Te2. The subtle change in stoichometry in Fe-Ag
sublattice changes magnetic ground state but not
conductivity, giving further insight into the semiconducting
gap mechanism.},
