Artificial superlattices of LaFeO3-LaMnO3 were formed on SrTiO3(111), (100), and (110) substrates with various stacking periodicity using a pulsed laser deposition technique, and their magnetic properties were controlled by altering the ordering of magnetic ions (Fe or Mn). For superlattices constructed on the (111) plane, all the superlattices showed ferromagnetic (or ferrimagnetic) behaviors and the same Curie temperatures (TC) at 230 K. The magnetization was reduced as the stacking periodicity of the superlattices decreased. On the other hand, in the case of superlattices formed on (110) or (100) substrates, the increase of the spin frustration effect at the LaFeO3-LaMnO3 interface with decreasing the stacking periodicity caused a reduction of TC and magnetization. In particular, spin-glass-like behavior was observed in superlattices of less than 3/3 stacking periodicity.
