  We report the magnetic properties, electrical resistivity, and Vickers
microhardness of as-cast and annealed high-entropy alloys (HEAs) FeCoNiPd and
FeCoNiPt with the face-centered cubic structure. The heat treatment at 800
$^{\circ}$C does not largely affect the physical properties in each HEA. The
values of the Curie temperature and the saturation moment at 50 K are 955 K and
1.458 $\mu_\mathrm{B}$/f.u. for the annealed FeCoNiPd, and 851 K and 1.456
$\mu_\mathrm{B}$/f.u. for the annealed FeCoNiPt, respectively. Each HEA is a
soft ferromagnet and shows metallic resistivity. The electronic structure
calculations of both HEAs support the ferromagnetic ground states. The
comparisons between experimental and theoretical values are made for the Curie
temperature, the saturation moment, and the residual resistivity. The Vickers
microhardness of annealed FeCoNiPd and FeCoNiPt are both 188 HV. The hardness
vs. valence electron count (VEC) per atom plot of these HEAs does not largely
deviate from an expected universal relation forming a broad peak at
VEC$\sim$6.8. This study would give some hints on designing a soft
ferromagnetic HEA with high hardness.
