A MXene-BiFeO-ZnO nanocomposite photocatalyst served as a high-performance supercapacitor electrode.

MXenes have attracted considerable attention in the field of energy storage and conversion due to their high surface area, excellent electrical conductivity, and ability to intercalate various ions. However, simultaneously achieving high capacitance, rate capability, cycling stability, and mechanical flexibility is a significant challenge for designing MXene-based supercapacitors. In this article, we explored MXene-BiFeO-ZnO nanocomposites for both photocatalytic and electric double-layer supercapacitor applications.

Ferroelectricity in CaBaCoOby light non magnetic Zn doping.

CaBaCoO(CBCO) cobaltite shows a giant spin driven pyroelectric polarization below its ferrimagnetic transition temperature at 64 K. In the present study, we have investigated the structural, magnetic and electric polarization properties of light nonmagnetic Zn doped polycrystalline CaBaCoZnO(CBCZO) cobaltite. Neutron powder diffraction studies on the CBCZO show that the Zn occupies the Co2 sites which lowers the strength of the magnetic interactions between the bitetrahedral cobalt-axis chains.

Tailoring of magnetic orderings in Fe substituted GdMnO bulk samples towards room temperature.

The evolution of various magnetic ordering has been studied for the orthorhombic perovskite GdMn Fe O (0  ⩽  x  ⩽  0.7) system to obtain its comprehensive magnetic phase diagram. We observed that the substitution of Fe in GdMnO increases the antiferromagnetic Neel temperature (T ) from 40 K to above 400 K and importantly induces a spin-reorientation transition (T ) for x  ⩾  0.

Antisite disorder driven spontaneous exchange bias effect in La(2-x)Sr(x) CoMnO₆ (0 ⩽ x ⩽ 1).

Doping at the rare-earth site by divalent alkaline-earth ions in perovskite lattice has witnessed a variety of magnetic and electronic orders with spatially correlated charge, spin and orbital degrees of freedom. Here, we report an antisite disorder driven spontaneous exchange bias effect as a result of hole carrier (Sr(2+)) doping in La(2-x)Sr(x)CoMnO6 (0  <  x  <  1) double perovskites. X-ray diffraction and Raman spectroscopy have evidenced an increase in disorder with the increase of Sr content up to x  =  0.

The extrinsic origin of the magnetodielectric effect in the double perovskite La2NiMnO6.

A La(2)NiMnO(6) polycrystalline sample prepared by the sol-gel method showed monoclinic crystal structure with the P2(1)/n space group and a saturation magnetization of 4.63 μ(B)/f.u.
