The existence of strong spin-orbit coupling has brought the iridates to the forefront of materials research, whereas strong electronic correlation has proven to produce a plethora of novel properties within the manganites. The physical properties of interfaces between such materials were investigated by synthesizing a series of artificial superlattices consisting of the 5d paramagnetic metal SrIrO₃ and 3d antiferromagnetic insulators AMnO₃, where A = Sr or La. Through our experimental investigations by x-ray diffraction, SQUID magnetometry, dc-transport, x-ray circular dichroism, and polarized neutron reflectometry measurements, both novel magnetic and transport properties were observed, which drastically differ from those of the constituent materials and are highly sensitive to the degree of dimensional confinement within the superlattices. Here I will present these results and discuss the implications of these intriguing magnetic and electronic properties.
