“…However, there are few studies related to half‐metallic ferromagnetic (HMF) and optical properties of LAO after doping with TM. [ 24–26 ] Zylberberg and Zuo‐Guang modulated the characteristics of LAO by doping of bismuth at La site and concluded the increased dielectric properties after doping. [ 27 ] Furthermore, Sandeep et al [ 28 ] theoretically studied the effect of concentration‐dependent Nd substitution on structural stability, magnetic, and electronic features of cubic phase of lanthanum aluminate using mBJ + U approximation.…”

The optoelectronic and magnetic features of La1‐xVxAlO3 (x=12.5, 25, 50, 75%) perovskites is investigated within density functional theory (DFT) using generalized gradient approximation by Perdew–Burke–Ernzerhof (PBE‐GGA). The effect of different percentages of Vanadium (V) substitution on the properties of LaAlO3 is studied and stability is confirmed through formation energies. The spin polarized band structure of La1‐xVxAlO3 (x=12.5, 25, 50, 75%) elucidate their half metallic ferromagnetic character. Furthermore, the optical performance of given compounds is explored by optical parameters like dielectric function, optical conductivity, refractive index, reflectivity, absorption and extinction coefficients. The obtained results make these compounds suitable for optoelectronic applications. It is observed that the determined magnetic moment in La1‐xVxAlO3 is mainly due to the V‐3d states. The regulated reduction in bandgap (Eg) with the upsurge of V doping and half metallic ferromagnetic nature make them appropriate for spintronic and magnetic devices.This article is protected by copyright.

“…In recent years, diluted magnetic semiconductors have obtained much consideration due to their applications in spintronics devices [8,9]. Moreover, induction of ferromagnetism in nonmagnetic Perovskites compound is significant from experimentally and theoretically prospective because of spin functionality addition to host crystal [10][11][12][13]. In addition to this, multiferroic compounds are being obtained by doping of transition metal (TM) [14].…”

"The magnetic, electronic, and optical properties of Cr doped LaAlO3 are examined by Full Potential linearized augmented plane wave (FP-LAPW) method within Density functional theory (DFT). The pure compound (LaAlO3) is doped with different concentrations of chromium (Cr) to examine the doping effects on its characteristics. The calculations of band structure (BS) and density of states show Cr has major contribution while La, Al and O atoms have little involvement in the states near Fermi level. The magnetic features revealed that Cr plays major participation in ferromagnetic nature of LaCrxAl1-xO3. The results of electronic and optical revealed that the compound under study is suitable for spintronics and optoelectronics applications. "

“…[13] Limited studies have been observed to date on the ferromagnetic and optical properties of the transition metal-doped LaAlO 3 . [16][17][18] Hong-Sheng et al studied the modification of the band gap in β -SiC and reported the change from an indirect to a direct band gap and the decrease of the energy band gap with doping the N-atom for the C atom. [19] Fang et al have satisfactorily explained the manifestation of an additional absorption peak in the experiments through the doping studies of KMgF 3 .…”

The structural, electronic, and magnetic properties of the Nd-doped Rare earth aluminate, La 1−x Nd x AlO 3 (x = 0% to 100%) alloys are studied using the full potential linearized augmented plane wave (FP-LAPW) method within the density functional theory. The effects of the Nd substitution in LaAlO 3 are studied using the supercell calculations. The computed electronic structure with the modified Becke-Johnson (mBJ) potential based approximation indicates that the La 1−x Nd x AlO 3 alloys may possess half-metallic (HM) behaviors when doped with Nd of a finite density of states at the Fermi level (E F ). The direct and indirect band gaps are studied each as a function of x which is the concentration of Nddoped LaAlO 3 . The calculated magnetic moments in the La 1−x Nd x AlO 3 alloys are found to arise mainly from the Nd-4f state. A probable half-metallic nature is suggested for each of these systems with supportive integral magnetic moments and highly spin-polarized electronic structures in these doped systems at E F . The observed decrease of the band gap with the increase in the concentration of Nd doping in LaAlO 3 is a suitable technique for harnessing useful spintronic and magnetic devices.
