Filtering of canted magnetic phase of SpFeMn(C2O4)3 in membrane nanopores

Ordered arrays of nanowires of pure SpFeMn(C2O4)3 collinear antiferromagnet have been synthesized in pores of anodized aluminum oxide (AAO) 20 nm and 200 nm in diameter. It was found that the growth of spin-canted phase presented in the bulk samples is suppressed in nanowires. The decrease in the nanowires diameter results in magneto-crystalline anisotropy increase.
