Query: Magnetic Structure and dielectric properties of antiferromagnetic FeCrO3   We report the enhancement of N\'eel temperature of Cr2O3 by replacing 50% of
Cr by Fe prepared by sol-gel method. The structural analysis by neutron
diffraction has revealed that FeCrO3 belongs to a corundum structure (R-3c
space group) with an antiferromagnetic spin structure having collinear spins
along a-axis with propagation vector k=0; the high-temperature magnetisation
study indicated a N\'eel temperature of 560 K. The enhancement in N\'eel
temperature has been attributed to the strong orbital hybridization that leads
to change in nearest neighbor bond angle and bond distances. Impedance
spectroscopy has revealed conduction mechanism at low temperature is due to the
polaron hopping while extrinsic contributions from the Maxwell-Wagner dominant
at high temperatures
