The decrease in the size of R III was found to increase the distortion of o- RMnO 3 with a decrease in the Mn O Mn bond angle from 144.3掳 for Dy to 140.3掳 for Lu. All the hexagonal and orthorhombic RMnO 3 phases exhibited antiferromagnetic characteristics at low temperatures....
GdMnO3 (hereafter designated by GMO) has attracted much attention with the aim to strain-engineering its properties, as its Mn-O-Mn bond angle sets it at the border line between spontaneous multiferroics TbMnO3 and DyMnO3, and the magnetic-field induced multiferroic EuMnO37,8,9. At room ...
ion-water bonding and solute drift motion, we here consider the O:HO bond relaxation and polarization by extending our efforts to the ionic electrification of NaX(X = HSO4, NO3, ClO4, SCN) complex salts, at different concentrations using Raman spectrometrics and surface contact angle measurement...
Due to changes in bond angle and bond lengths on substituting Mg, there is a slight decrease in the distortion of MnO5polyhedra. Magnetic measurements show that the N茅el temperature (TN) increases marginally from 85K forx=0.00 to 89K forx=0.05 sample.doi:10.1016/j.physb.2014.03.012Bhumi...

increasing angle of the MnO5,the length of the Mn-O bond is longer and the interaction of ferromagnetic and antiferromagnetic exists in the system.However, the YMn1-xCrxO3 samples are found to increase in ferromagnetic transition temperature due to the enhancement of double exchange between Cr3+...
The hopping between Mn3+ and Mn4+ sites is controlled by the Mn–O–Mn bond angle. The magnetoresistance in 8.5 kOe fields varies from 15 to 25 percent over the temperature range 300 K to 80 K. The conduction mechanism can be understood by using the correlated small polaron model. The ...

What is the bond angle in a tetrahedral molecule? What is the molecular shape of CF2Cl2? What is the hybridization of AlCl3? What is the electron geometry of ClF_3? What is the molecular formula of benzene? What is molecular structure? What is the molecular geometry (shape) of the phosp...
Such gradual suppression of octahedral tilt has been observed for the BiFeO3/(LaSr)MnO3 interface30, where the Fe-O-Fe bond angle was modified over a distance of 10 unit cells by 6° near the interface. Recently a similar suppression of octahedral tilt and its polar effect has been reporte...
