Temperature dependent structural properties of MnMO(M = Cr and Fe).

The polycrystalline samples of MnCrO(MCO) and MnFeO(MFO) have been investigated for their temperature dependent magnetic and structural properties. The Cr and Fe substitutions have significant effect on the magnetic and structural properties of MnO. Like pristine MnO, the Cr and Fe substituted samples MCO and MFO also exhibit two antiferromagnetic transitions; one at ∼77 K, ∼80 K, respectively and another at ∼40 K.

Structural correlations in the enhancement of ferroelectric property of Sr doped BaTiO.

The effect of Sr doping in BaTiO(BTO) with nominal compositions BaSrTiO(BSTO) have been explored on its structural, lattice vibration, dielectric, ferroelectric and electrocaloric properties. The temperature dependent dielectric results elucidate the enhancement in dielectric constant and exhibit three frequency independent transitions around 335, 250 and 185 K, which are related to different structural transitions. All these transitions occur at lower temperature as compared with pristine BTO, however; remnant electric polarization () of BSTO is much higher than in BTO.

Enhancement of magnetoelectric coupling in Cr doped MnO.

The effect of Cr doping has been undertaken to investigate its effect on the structural, magnetic, dielectric and magnetoelectric properties of newly discovered multiferroics material α-MnO. The Cr doping modifies the room temperature crystal symmetry i.e.

Exact Passive-Aggressive Algorithms for Ordinal Regression Using Interval Labels.

In this article, we propose exact passive-aggressive (PA) online algorithms for ordinal regression. The proposed algorithms can be used even when we have interval labels instead of actual labels for example. The proposed algorithms solve a convex optimization problem at every trial.
