| Abstract | A new perovskite-type oxide, CaCu3Cr2Nb2O12, has been synthesized at 10 GPa and 1100 degrees C. The compound crystallizes in space group Im3 with 1:3 ordered Ca and Cu cations at the A sites and disordered Nb cations at the octahedral B sites. CaCu3Cr2Nb2O12 exhibits a paramagnetic-ferrimagnetic transition around 192.3 K and the Arrott plots manifest this transition is a second-order transition. We investigate the critical behavior of CaCu3Cr2Nb2O12 using the modified Arrott plots, Kouvel-Fisher plot, and the theory. The estimated critical exponents fi, y and 6, which yield fi = 0.465 +/- 0.006, y = 1.312 +/- 0.019 6= 3.833 +/- 0.019 with TC = 197 K, fall within the predicted values from the mean-field model and dimensional Heisenberg model. The renormalization group analysis suggests that the exchange interaction decays as J(r) similar to r-4.871, indicating the magnetic interactions may be long-range coupling in CaCu3Cr2Nb2O12. |
