Polycrystalline, MgCu2-type multicomponent Laves phase intermetallic compound Gd0.2Tb0.2Dy0.2Ho0.2Er0.2Al2 (cubic, space group Fd-3m, cF24) orders ferromagnetically at 80 K ( TC ). The TC is found to be approximately equal to the average of ferromagnetic transition temperatures of the individual components RAl2 (R = Gd, Tb, Dy, Ho, and Er). Heat capacity shows a λ -type transition around TC. The second-order nature of the transition has been confirmed by plotting universal curve with the isothermal magnetic entropy change versus temperature data. Electrical resistivity is metal-like in the paramagnetic region. Both electrical resistance and thermopower shows a slope change near TC. Temperature dependence of thermal conductivity of Gd0.2Tb0.2Dy0.2Ho0.2Er0.2Al2 is as that of a metal.
