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...

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 ...
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 change of the resistivity with the x was explained by a variation in the hopping integral between Mn3+ and Mn4+, which is dependent on the Mn-O-Mn bond angle affected by the average A-site ionic size. Remarkably, the Sm-doped manganites showed an antiferromagnetic transition by the ...
