Study on the Room Temperature Phase of LaNbO_4 Crystals(Physics)

この論文をさがす

説明

The precise X-ray analyses with a precession camera and a four-circle diffractometer prove that the space group of LaNbO_4 crystals at room temperature is non-centrosymmetric Ic or Ia. The polarized Raman Spectra suggest that this acentric structure is very close to centrosymmetric one.
