“…Another possibility which could affect the phonon lifetime is electron-phonon coupling. The earlier research on TCMO established the insulating nature of the system which eliminates the prospecting of electron-phonon coupling [26]. Hence, the observed phonon anomaly in TCMO is solely ascribed by the coupling between spin and phonon.…”

The double perovskite compound Tb 2 CoMnO 6 has been investigated using x-ray absorption spectroscopy (XAS), Raman spectroscopy, magnetic measurements and ab initio band structure calculations. It is observed that both anti-ferromagnetic (AFM) and ferromagnetic (FM) phase coexist in this material. The presence of anti-site disorder (ASD) has been established from the analysis of neutron diffraction data. Moreover, a prominent metamagnetic transition is observed in the M(H ) behavior that has been explained with the drastic reorientation of the pinned domain which are aligned antiparallel by the antiphase boundaries (APBs) at zero field. The ASD further gives rise to spin frustration at low temperature which leads to the re-entrant cluster glass ∼33 K. The coupling between phononic degree of freedom and spin in the system has also been demonstrated. It is observed that the theoretical calculation is consistent with that of the experimentally observed behavior.

“…Furthermore, Tb 2 CoMnO 6 (TCMO) is less explored DP system compared to La and Y based DP [24][25][26]. Recently, some interesting properties such as; large rotational magnetocaloric effect (MCE), relaxor glass transition in TCMO have been reported [36][37][38][39].…”

“…4 The double perovskite Tb 2 MnCoO 6 shows meta-magnetic properties and improved conductivity than the single perovskite TbCoO 3 . 5 The effect of Mg mixing on the band gap modulation traits of polycrystalline ceramic Sr 2 NiWO 6 is also studied. 6 The reason behind this variation was assigned to the comparatively bigger size of Mg 2+ cations that decreased the excitation limit for the valence electrons.…”

The multiferroic nature of the Mg2FeNbO6 complex oxide ceramic, prepared by a mixed oxide reaction route is presented. A phase transformation to the tetragonal symmetry was identified from refinement analysis. The optical band gap was estimated to be 1.58 eV with the direct allowed transition consideration. From the temperature-dependent dielectric parameter study, magnetic phase transitions at various Tc values were seen, together with some glassy dynamics. The CIS spectroscopy revealed the dominance of grains toward the complex impedance response of the composite. The conductivity of the compound was found to be following Jonscher’s universal power quite ideally. The plot of μB/unit mass versus manifests itself as a weak but well-saturated magnetic ordering in the ceramic, with a low retentivity value of 0.0286 emu/gm. The multiferroic nature of the oxide material is confirmed by the existence of a room temperature (P-E) hysteresis loop, with remnant polarization of Pr=1.2 µC/Cm2.

Increased energy consumption due to rise in global population and rapidly increasing living standards has resulted in fast depletion of fossil fuel sources. Energy-storage technologies and advanced material engineering both have a significant and promising contribution worldwide to meet the issues of sustainable energy production. [1,2] Energy-storage systems, including batteries as well as supercapacitors, are among the more viable and ecologically favorable green energy solutions. Batteries supply adequate energy quantity although capacitors provide superior-quality power quantity, yet in difference, the power quantity in batteries and capacitors are lesser. Supercapacitors, on account of their distinctive competence, proved to be significant due to the integrated benefits of both. [3,4] They have wide and crucial usages in compact electronics, smart integrated devices, and other high-tech fields due to their specific properties, which consist of great capacity, high level of power density, long-lasting life period, superior charge and discharge capability, negligible maintenance, and economic and environmental safety, thus, they have globally turned into a point of research discussion in the field of energy storage. [5,6] MXene-based nanomaterials for supercapacitors have also attracted a lot of interest due to their high density, metallic conductivity, and hydrophilic nature. [7,8] Double perovskite metal oxides seem to be a kind of perovskite that has a unique structure. The ABO 3 configuration of prevalent perovskite oxide is taken by an alkaline earth/rare earth ion (Ba, Sr, Y, La, etc.) on A site and transition metal ion (Mn, Co, Fe, Cu, etc.) on B site. The characteristics of double perovskites are heavily influenced by the components that occupy these positions. The octahedral core of the adjacent six oxygen atoms is occupied by BB 0 site ions. Nonetheless, in the A 2 BB 0 O 6 composition of double perovskite metal oxides, the BB 0 sites are filled by two transition metals with an atomic ratio of 1:1. An extensive study has recently been undertaken on double perovskite oxide nanomaterials to better comprehend their energy storage, magnetic, and electrical characteristics. [9][10][11] The double perovskite materials were already synthesized through a variety of processes, including the solid-state approach, the sol-gel strategy, high-pressure fabrication, the solvothermal/ hydrothermal approach, etc. Numerous perovskite compounds had already been studied for energy-storage applications so far. [12][13][14] Although double perovskite oxide nanomaterials have shown potential for energy-storage purposes, research concerning them has been minimal. [15][16][17][18][19][20] The energy-storage and magnetic performances of some double perovskites containing yttrium at A positions, such as Y 2 NiMnO 6 , Y 2 CuMnO 6 , and Y 2 CoNiO 6 , have already been investigated.
