Abstract: We theoretically investigate the Josephson effect of massive pseudospin-1 fermions in the ferromagneticmodel, which includes the- and-type fermions, via the modulation of parameter. Our results first reveal that the non-ferromagnetic junction is invariably in thestate, with the supercurrent vanishing when the mass magnitudeor the junction lengthis sufficiently large. In the ferromagnetic junction, thestate transition can be induced by varying the value of, with this state transition strongly influenced byand the Fermi energy. Particularly, a largeis shown to cause the disappearance of both thestate transition and the supercurrent itself. Furthermore, we demonstrate the distinctive supercurrent properties that characterize the- and-type fermions. These results may provide valuable insights for developing quantum electronic devices based on the superconducting properties ofmaterials with massive pseudospin-1 fermions.
