Effect of Ti Doping on the magnetic and structural properties of LaCrO3 — •Patrick Reuvekamp1, Reinhard K Kremer1, Fereidoon S.

We report on the preparation as well as the structural and magnetic characterization of titanium doped lanthanum chromium oxides. Heat capacity, magnetic susceptibility, XRD and EPR were used to characterize the polycrystalline samples of LaCr1−xTixO3 (x=0,0.1,0.2). LaCrO3 undergoes a structural phase transition at Tst ∼ 560 K and canted antiferromagnetic order below TN ≃ 290 K. In contrast to reports in literature, Ti doping reduces Tst and decreases TN to ∼ 230 K.
