  In this study, we determined the different physical characteristics of
nanoscale layered mixed Fe-Co layers of orthoferrite SmFe0.5Co0.5O3 based on
magnetic and dielectric measurements.Magnetization analyzes showed that the
system was antiferromagnetic with a magnetic transition around 310 K and two
spin-reorientation transitions at around 192 K and 22 K.In this phase, the
antisymmetric exchange interaction induced weak ferromagnetism due to canting
of the magnetic spins in a similar manner to the Ln-Fe-Co system. Importantly,
this nanoscale layered perovskite also exhibited a positive magneto-dielectric
effect of around 2.5 % (100 K) and the value decreased on both sides of this
temperature.We analyzed the conditions related to the existence of magnetic and
dielectric coupling in terms of the magnetic interactions between the cations
as well as the spin-lattice interactions in the low temperature range.
