Local Probing ErCrO3

Local distortions in perovskite-like orthochromites are of extreme importance for the properties they exhibit. Here, we present results structural and DC magnetisation measurements combined with local probe studies polycrystalline ErCrO3. The electric field gradient (EFG) parameters’ evolution temperature shows two clear signals environment changes, one at ferroelectric phase transition (TFE) other below 250 K. At claimed TFE, EFG changed from a slightly distorted axial symmetric to an symmetry (evidence that point-symmetry crystal might have changed). around K, observed development magnetic hyperfine (MHF) change one. These observations rather line our measurements, as relatively strong coercive was well above Cr sub-lattice ordering temperature.
