Manganese ferrite spinel has been synthesized by using low grade manganese ore and ferric oxide as sources of manganese oxide and iron oxide through solid state reaction route by taking manganese and iron mole ratio of 1:2 respectively. The impact of sintering temperature on phase composition and particle size is investigated. Similarly, the impact of frequency on dielectric constant, dielectric loss, AC (alternating current) conductivity and tangent losses is also investigated. The results shows the presence of spinel structure manganese ferrite (MnFe2O4) as the major phase for the sample sintered at 1200 °C. It has been established that the crystallite size increase with rise in sintering temperature. The surface morphology of the sample sintered at 1200 °C show pyramidal and triangular shape grains. The dielectric constant (εʹ) and dielectric losses (εʹʹ) were observed to decrease with increasing the sintering temperature and frequency. Furthermore, the AC (alternating current) conductivity was found to rise with rise in applied frequency. On the other hand, the tangent losses falls considerably with rise in applied frequency.

“…2(b)) is linear across the full measured range (µ 0 H = ± 7 T), with no observable hysteresis. Previous chemical analysis on a crystal grown in a very similar manner showed Li:Cu = 1.99:1.01 [56], and the lack of any low-temperature ferromagnetism suggests a fully occupied oxygen site [58]. The measured T N is elevated compared to previous results for crystals grown at lower pressures (≈ 8 -9 K) [29,[58][59][60], likely reflecting an optimized stoichiometry.…”

Here we report a study of the spin dynamics in the ferromagnetic chain compound Li2CuO2. Inelastic neutron scattering measurements allow for the spin Hamiltonian to be determined using a J1 − J2 XXZ-Heisenberg spin chain model with weak inter-chain interactions. The primary exchange parameters determined from our data are qualitatively consistent with those of W. E. A. Lorentz et al. Europhys. Lett. 88, 37002 (2009), and our data allow for the resolution of additional inter-chain exchange interactions. We also observe the formation of two-and three-magnon bound states, stabilized by the weak, Ising-like exchange anisotropy of the nearestneighbor intra-chain interaction. While the two-magnon bound state exists only in the magnetically ordered phase of this material, the three-magnon state persists in a finite temperature regime above TN , indicating an unconventional character. Our results establish Li2CuO2as an experimental platform for the study of exchange anisotropy-stabilized bound states in a ferromagnetic chain.

“…The magnetic moment on oxygen atoms is generated from oxygen vacancies [23], and Ca atoms carry a negligible magnetic moment. The magnetic moments within GGA and GGA+U methods summarized in Table 2 show that the magnetic moment of Ca 2 FeIrO 6 is 6.015 µ B .…”

This study aimed to explore the electronic, magnetic, and magneto-optical properties of double perovskites Ca2FeIrO6 and Ca2CoIrO6 to examine their potential applications in spintronic and photovoltaic devices. The calculations were done using the full-potential linearized augmented plane wave within the density functional theory. For the electronic exchange-correlation function, we used the generalized gradient approximation (GGA) and GGA+U (Hubbard potential), and spin-orbit coupling (SOC). The study showed that Ca2FeIrO6 and Ca2CoIrO6 exhibit a monoclinic structure (space group P21/c). The structure relaxation shows an antiferromagnetic behavior in both systems with a magnetic moment of about 6.00 µB for Ca2FeIrO6 and 4.00 µB for Ca2CoIrO6 by using GGA+U approximation. GGA and GGA+U computations predict half-metallic behavior for both. The magneto-optical polar Kerr effect (MOKE) was examined by studying the variation of Kerr and ellipticity rotation. The Kerr rotation angle is 1.3° at 4.82 eV and −1.21° at 4.3 eV, and the ellipticity angle is −1.21° at 4.3 eV for Ca2FeIrO6. In the case of Ca2CoIrO6, the Kerr rotation angle is −1.04° at 4.05 eV; the significant Kerr rotation in both 1 Springer Nature 2021 L A T E X template Properties of the Double Perovskites Ca 2 TMIrO 6 (TM=Fe, Co) compounds may suggest the application of these materials in optoelec-tronics bias. The named compounds have the potential application in the field of spintronics and its devices, as in optoelectronics technologies.
