  The existence of exceptional points (EPs) ${-}$ where both eigenvalues and
eigenvectors converge ${-}$ is a key characteristic of non-Hermitian physics. A
newly-discovered class of magnets ${-}$ termed as altermagnets (AMs) ${-}$ are
characterized by a net zero magnetization as well as spin-split bands. In this
study, we propose the emergence of non-Hermitian physics at AM-ferromagnet (FM)
junctions. We discover that such a junction hosts tunable EPs. We demonstrate
that the positions of these emergent EPs can be tuned using an external applied
magnetic field and show that for a critical value of the applied magnetic field
the EPs can annihilate. Notably, the number and position of the EPs crucially
depends on the type of AM and its orientation with respect to the FM. Our work
puts forth a promising platform of exploration of non-Hermitian physics in an
emerging class of magnetic materials.
