The experimental existence and stability of the quantum criticality point ofthe two-channel Kondo (2CK) effect displaying exotic non-Fermi liquid physicshas been buried in persistent confusion despite the intensive theoretical andexperimental efforts in past three decades. Here we report an experimentalrealization of the two-level system scattering-induced orbital 2CK effect in aferromagnetic L10-MnGa film, which is signified by a magnetic field-independentresistivity upturn that has a logarithmic and square-root temperaturedependence beyond and below the Kondo temperature of ~14.5 K, respectively. Ourresult not only evidences the robust existence of orbital 2CK effect even inthe presence of strong magnetic fields and long-range ferromagnetic orderingbut also extends the scope of 2CK host materials from nonmagnetic nanoscalepoint contacts to diffusive conductors of disordered alloys.
