Title

To study the effect of Mn doping on the temperature and field dependent re-orientation of orthoferrite NdFe0.5Mn0.5O3.

Abstract

The study is based on the Mn substituted orthoferrite NdFe0.5Mn0.5O3. Substition of Mn at the Fe site alters the magnetic properties, though the main characteristic G-type ordering is similar to NdFeO3. Neutron diffraction data (wavelength ~ 1.24Å) reveal that below 250 K, the Fe/Mn spins order in Gamma1(AxGyCz) representation, unlike the usual Gamma4representation observed in NdFeO3 and other orthoferrites. Below 100 K, spins undergo a reorientation and the magnetic structure coexists as Gamma1+ Gamma2, while at 6 K the magnetic structure belongs to only Gamma2(FxCyGz) representation. A second order transition Gamma1 to Gamma2, cannot be explained in terms of Nd-Fe(Mn) isotropic and antisymmetric interactions alone. Also a primary issue here is the simple Gy-type collinear spin arrangement seen below 250 K. without Ax/Cz spin components cannot couple with the Nd spins and cause the spin reorientation transition. It is essential to verify the presence of Cz/Cy-type (010),(100) Bragg peaks, which may be possible with better resolution data. In addition, it would be interesting to study the effect of magnetic field on magnetic structure and reorientation in NdFe0.5Mn0.5O3.
