The high-spin states in odd-odd \(^{194}\)Tl nucleus have been studied by populating them using the \(^{185,187}\)Re(\(^{13}\)C, xn) reactions at 75 MeV of beam energy. \(\gamma-\gamma\) coincidence measurement has been performed using the INGA array with a digital data acquisition system to record the time stamped data. Definite spin-parity assignment of the levels was made from the DCO ratio and the IPDCO ratio measurements. The level scheme of \(^{194}\)Tl has been extended up to 4.1 MeV in excitation energy including 19 new gamma ray transitions. The \(\pi h_{9/2} \otimes \nu i_{13/2}\) band, in the neighboring odd-odd Tl isotopes show very similar properties in both experimental observables and calculated shapes. Two new band structures, with 6-quasiparticle configuration, have been observed for the first time in \(^{194}\)Tl. One of these bands has the characteristics of a magnetic rotational band. The cranked shell model calculations, using a deformed Woods-Saxon potential, have been performed to obtain the total Routhian surfaces in order to study the shapes of the bands and the band crossing in \(^{194}\)Tl. The semiclassical formalism has been used to describe the magnetic rotational band.
