  Ferromagnetic films of L10-ordered MnGa and MnAl that exhibit giant
perpendicular magnetic anisotropy and great controllability in the magnetism
and structural disorders show promise not only in the applications in magnetic
recording, permanent magnets and spintronics, but also in controllable studies
of disorder-relevant electrical transport phenomena. In this article, we review
the intriguing experimental observations of the orbital two-channel Kondo
effect and anomalous Hall effect in L10-ordered MnGa and MnAl thin films with
perpendicular magnetic anisotropy. We also give a perspective with regards to
the future technological and fundamental applications of these perpendicularly
magnetized Mn-based binary alloy films.
