In the organic charge transfer salt k-(BETS)2Mn[N(CN)2]3 the metallic conductivity is provided by itinerant pi-electrons in the layers of BETS molecules, whereas magnetization is largely dominated by the localized d-electrons of the Mn2+ ions in the

A new metallic radical cation salt $\kappa$-(BETS)$_2$Co$_{0.13}$Mn$_{0.87}$[N(CN)$_2$]$_3$, where BETS is bis(ethylenedithio)tetraselenafulvalene, C$_{10}$S$_4$Se$_4$H$_8$, has been synthesized. In this salt, a part of Mn$^{2+}$ ions are replaced by

We present magnetoresistance studies of the quasi-two-dimensional organic conductor $\kappa$-(BETS)$_2$Mn[N(CN)$_2$]$_3$, where BETS stands for bis\-(ethylene\-dithio)\-tetra\-selena\-fulvalene. Under a moderate pressure of 1.4\,kbar, required for st

Peculiarities observed in the field dependencies of the magnetic torque in k-(BETS)2Mn[N(CN)2]3 measured at T=1.5K, H=0-150kOe, have been explained from the viewpoint of the two interacting spin subsystems, one associated with d-electron spins of Mn2

The low-temperature charge-density-wave (CDW) state in the layered organic metals $\alpha $-(BEDT-TTF)$_2$MHg(SCN)$_4$ has been studied by means of the Shubnikov -- de Haas and de Haas -- van Alphen effects. In addition to the dominant alpha-frequenc

Magnetic properties of the conduction pi-electron system of kappa-BETS)2Mn[N(CN)2]3 have been probed using 13C NMR. At ambient pressure, the metal-insulator transition observed in the resistivity measurements below T~23K is shown to be accompanied by

A complex study of magnetic properties including dc magnetization, 1H NMR and magnetic torque measurements has been performed for the organic conductor kappa-(BETS)2Mn[N(CN)2]3 which undergoes a metal-insulator transition at T_MI~25K. NMR and the mag

The angle-dependent interlayer magnetoresistance of the layered organic metal $\alpha$-(BEDT-TTF)$_2$KHg(SCN)$_4$ is found to undergo a dramatic change from the classical conventional behavior at low magnetic fields to an anomalous one at high fields

We present comparative studies of the orientation effect of a strong magnetic field on the interlayer resistance of $\alpha$-(BEDT-TTF)$_2$KHg(SCN)$_4$ samples characterized by different crystal quality. We find striking differences in their behavior

Layered organic conductors (BEDO-TTF)_2ReO_4*H_2O (metal) and (BEDT-TTF)_xDy(NO_3)_z (paramagnetic insulator) are studied by CW-EPR and SQUID methods. A correlation in resonance and transport properties of both compounds is attributed to a similar me
