  Current sheets are an essential element of the planetary magnetotails, where
strong plasma currents self-consistently support magnetic field gradients. The
current sheet configuration is determined by plasma populations that contribute
to the current density. The most commonly investigated configuration is
supported by diamagnetic cross-field currents of hot ions, typical for the
magnetospheres of magnetized planets. In this study, we examine a new type of
the current sheet configuration supported by field-aligned currents from
electron streams in the Jovian magnetodisk. Such bi-directional streams
increase the electron thermal anisotropy close to the fire-hose instability
threshold and lead to strong magnetic field shear. The current sheet
configuration supported by electron streams is nearly force-free, with B=const
across the sheet. Using Juno plasma and magnetic field measurements, we
investigate the internal structure of such current sheets and discuss possible
mechanisms for their formation.
