23 Jun 2016 | | Abstract: | The ground state properties of $kappa$-(BETS)$_2$FeCl$_4$ below the N’eel
temperature $T_N=0.47,mathrm{K}$ was studied by interlayer electrical
resistance measurements $R$ under magnetic field. The measurements revealed no
evidence of bulk superconductivity, however, a linear temperature dependence of
$R(T)$ was observed down to 30 mK. In the AFM state SdH oscillations were
found, which suggest a reconstruction of the FS due to the magnetic ordering.
The $H$-$T$ phase diagram for the three principal crystal axes could be drawn.
For magnetic field along the easy axis a spin-flop transition was found. A
magnetic field perpendicular to the conducting layers caused an increase of
$T_N$ for small fields. The results are discussed in comparison to the sister
compound $kappa$-(BETS)$_2$FeBr$_4$. | | Source: | arXiv, 1606.7331 | | Services: | Forum | Review | PDF | Favorites | |
