Abstract
The magnetic properties of the Fe1−xAgxCr2S4 (0 < x < 0.2) solid solution were investigated in the temperature range 4–300 K in a DC field of 0.1 and 45 kOe. Fe1−xAgxCr2S4 is characterized by the transition temperature from the paramagnetic to the ferromagnetic state (Tc) and the irreversibility temperature (Tirr). The replacement of iron with silver ions in Fe1−xAgxCr2S4 leads to an increase in the Curie temperatures from 185 K (x = 0) to 216 K (x = 0.2) and Tcusp from 45 K (x = 0) to 125 K (x = 0.2). A section of the Fe1−xAgxCr2S4 magnetic phase diagram in the region under study has been constructed. The diagram reveals the following regions: paramagnetic, ferromagnetic, region of conditionally recurrent spin-glass (SG), and below 10 K a region associated with orbital ordering.
