看到论文里提到 OO phase transition 是什么样的相变？请各位虫虫帮忙

前文有一处提到“OO ”如下： This corresponds to the antiferromagnetic (AFM) ordering of the magnetic moment of one of the two unpaired electrons of the chromium in the low-temperature phase segregated with tetragonal structure, as has been previously demonstrated from neutron and synchrotron data.23 In this last study, orbital ordering is suggested to drive a cubic to tetragonal (orbitally ordered, OO) phase transition, with the coexistence of both phases at low temperature. The phase fraction appears to depend on the pressure employed for the sample synthesis. 后文当中提到“ OO phase transition”如下： However, in a very recent study, optical conductivity and reflectivity measurements seem to indicate that “CaCrO3 is metallic, despite being antiferromagnetic” and “that the negative dependence of the resistivity against temperature is due to grain boundary scattering”.40 The PXRD data collected in our samples suggest a room temperature OO phase transition due to the coupling of the JT effect with the orthorhombic distortion.24 这里提到的“OO phase transition ”是指什么相变？请各位虫虫帮忙解答 |
