An ab initio linearized augmented plane-wave method has been employed to calculate the electronic and magnetic structures of both face-centered-cubic and body-centered-cubic ${\mathrm{Fe}}_{1-x}{\mathrm{Pd}}_x$ alloys with $x=0.25,$ 0.50, and 0.75, respectively. Decreasing the Pd content in ${\mathrm{Fe}}_{1-x}{\mathrm{Pd}}_x$ alloy from $x=1,$ the magnetic ordering of fcc ${\mathrm{Fe}}_{1-x}{\mathrm{Pd}}_x$ changes from paramagnetism to ferromagnetism, ferrimagnetism, and finally to antiferromagnetism. However, the magnetism of bcc ${\mathrm{Fe}}_{1-x}{\mathrm{Pd}}_x$ changes simply from paramagnetism to ferromagnetism.
