(TMTSF)2FSO3 is very special in that its electric transport properties are described by electrons from two-dimensional Fermi surfaces (FS) whereas those in most other Bechgaard salts are intrinsically explained with electrons from weakly warped quasi-one- dimensional FS. Conventional Shubnikov-dc Haas oscillations, described with the Lifshitz-Kosevich formula, has been observed. In this study, we measured magnetoresistance along the least conducting direction (c*) under pressures of up to 11 kbars and magnetic fields of up to 55 T, generated in a pulsed magnet, and found that the oscillations preserved two-dimensional nature to the highest measured field. There is no field-induced electronic transition. Pressure dependence and magnetic field dependence of parameters of oscillations are presented and discussed.
