  In this work, we study the effects of a transverse magnetic field in a Kondo
lattice model with two $f$ orbitals interacting with the conduction electrons.
The $f$ electrons that are present on the same site interact through Hund's
coupling, while on neighboring sites they interact through intersite exchange.
We consider here that part of $f$ electrons are localized (orbital 1) while
another part (orbital 2) are delocalized, as it is frequent in uranium systems.
Then, only electrons in the localized orbital 1 interact through exchange
interaction with the neighboring ones, while electrons in orbital 2 are coupled
with conduction electrons through a Kondo interaction. We obtain a solution
where ferromagnetism and Kondo effect coexist for small values of an applied
transverse magnetic field for $T\rightarrow0$. Increasing the transverse field,
two situations can be obtained when Kondo coupling vanishes: first, a
metamagnetic transition occurs just before or at the same time of the fully
polarized state, and second, a metamagnetic transition occurs when the spins
are already pointing out along the magnetic field.
