- Magnetic doping: 13% of spin-5/2 Mn is replaced with spin-3/2 Co in 뼉(BETS)2Mn[N(CN)2]3.
- Minor effect of the doping on crystal and band structure and conduction properties.
- Dramatic effect of the doping on the magnetic anisotropy.
- Potentiality to design different combinations of magnetic and conducting properties.
A new metallic radical cation salt κâ(BETS)2Co0.13Mn0.87[N(CN)2]3, where BETS is bis(ethylenedithio)tetraselenafulvalene, C10S4Se4H8, has been synthesized. In this salt, a part of Mn2+ ions are replaced by Co2+ which acts as a magnetic dopant with a different effective magnetic moment. Crystal structure, band structure, conducting and magnetic properties of the salt have been studied. Below 30 K the material undergoes a metal-insulator transition, which is suppressed by applying a pressure of â¼0.5 kbar, leading to a superconducting ground state. While the structural and conducting properties are very similar to those of the parent salt κâ(BETS)2Mn[N(CN)2]3, magnetic properties associated with localized moments in the anion layer are found to be surprisingly different.
