Si. Pesotskii et al., ANISOTROPY OF MAGNETORESISTANCE AND SHUBNIKOV-DE HAAS OSCILLATIONS INORGANIC METAL (ET)(3)CUCL4-CENTER-DOT-H2O, Acta Physica Polonica. A, 87(4-5), 1995, pp. 773-776
Behavior of the magnetoresistance has been studied in organic quasi tw
o-dimensional metal (ET)(3)CuCl4 . H2O. Shubnikov-de Haas oscillations
have been observed at the magnetic field directions near H \\ c. The
oscillations frequency at H \\ c equals 45 T that corresponds approx
imately to 1% of the first Brillouin zone cross-section. The angle dep
endence of the oscillations frequency allows one to imagine at least t
he part of Fermi surface in the form of cylinder with an axis along c
.
