  Spin-mediated charge-to-heat current conversion phenomena, i.e., the
anomalous Ettingshausen effect (AEE) and the anisotropic magneto-Peltier effect
(AMPE), have been investigated in various ferromagnetic Ni-Fe, Ni-Pt, Ni-Pd,
and Fe-Pt binary alloys at room temperature. When a charge current is applied
to a ferromagnetic conductor, the AMPE modulates the Peltier coefficient
depending on the angle between the directions of the charge current and
magnetization, while the AEE generates a heat current in the direction
perpendicular to both the charge current and magnetization. We observed the
strong material dependence of the thermoelectric conversion coefficients and
figures of merit of these phenomena. Among the ferromagnetic alloys used in
this study, Ni$_{95}$Pt$_{5}$ exhibits the largest AMPE of which the anisotropy
of the Peltier coefficient is $\sim 12\%$. In contrast, the magnitude of the
AEE signals is moderate in Ni$_{95}$Pt$_{5}$ but largest in Ni$_{75}$Pt$_{25}$
and Ni$_{50}$Fe$_{50}$. We discuss these behaviors by exploring the relations
between these charge-to-heat current conversion phenomena and other transport
as well as magnetic properties. This systematic study will provide a clue for
clarifying the mechanisms of the AMPE and AEE and for enhancing the
thermoelectric conversion efficiency of these phenomena.
