The calculation uses the static Ginzburg-Landau (GL) functional in the fixed-induction, negligible-self-field limit. An annular Gaussian suppression is parameterized by the dimensionless peak strength <span>({V}_{0})</span>, the ring radius <span>({r}_{p})</span> in units of the temperature-dependent coherence length <span>({xi}_{T})</span>, and the Gaussian width <span>(sigma)</span> in the same units. Candidate profiles are screened with a variational ansatz and the selected design is re-evaluated by a radial boundary-value problem (BVP).

In the range of moderate and high fields (up to 1 kOe), the difference ΔM between the upper and lower branches of the magnetization hysteresis loop is larger when the external magnetic field H is parallel to the normal of the texturing plane (H||N_TP) than when H is parallel to the texturing plane (H⊥N_TP). This magnetic anisotropy is typical for such textured superconductors. However, at small values of the maximum applied field H_max (up to 15 Oe at a temperature T = 78 K), an anomalous inversion of anisotropy has been found: ΔM(H||N_TP) &lt; ΔM(H⊥N_TP). It has been established that in the field range up to ~ 30 Oe (the first penetration field into Bi2223 crystallites is about 30 Oe at T = 78 K), the magnetic hysteresis is determined only by the magnetic flux trapped in the intercrystallite boundary subsystem.

The observed inverse anisotropy ΔM(H||N_TP) &lt; ΔM(H⊥N_TP) has been explained by the fact that the effective magnetic field into the intercrystallite boundaries is smaller for the H||N_TP orientation than for H⊥N_TP.

All compositions were found to crystallize in an orthorhombic perovskite-type structure (space group <i>Pnma</i>). Structural analysis revealed a systematic decrease in lattice parameters and orthorhombic distortion with increasing manganese content, accompanied by a reduction in the distortion of the MnO₆ octahedra associated with the Jahn–Teller (JT) effect. These changes are consistent with the proposed disproportionation reaction, 2Mn³⁺ → Mn²⁺ + Mn⁴⁺, which would reduce the fraction of JT-active Mn³⁺ ions and thereby contribute to the progressive weakening of the cooperative JT distortion, while the O′ structural state is retained throughout the entire compositional range. Magnetic measurements showed that stoichiometric SmMnO₃ exhibits antiferromagnetic ordering at T_N ≈ 57 K along with an additional magnetic contribution from the Sm³⁺ sublattice below 10 K. The introduction of excess manganese shifts the balance between competing antiferromagnetic and ferromagnetic interactions toward an increasing ferromagnetic contribution, promoted by Mn³⁺–O–Mn⁴⁺ double-exchange interactions and manifested in an increasingly magnetically inhomogeneous state. The observed correlation between the weakening of the JT-effect and the enhancement of ferromagnetic interactions highlights the crucial role of cation non-stoichiometry in controlling the magnetic state of SmMnO₃-based manganites.

The valuable improvements to High-Temperature Superconductor (HTS) materials would add, with higher working temperatures and critical magnetic fields, to the research and commercial aspects of the technologies. Little work has been done in investigating the impact of doping erbium (Er) on the properties of bulk and nano-layers of YBCO superconducting thin films on indium tin oxide (ITO) coated glass substrates. Thus, the pristine and Er-doped bulk and nano-layer YBCO superconductor material were perfectly synthesized utilizing a pulsed laser deposition (PLD) system to investigate the effect of various concentrations, 0.1%, 0.5%, and 1% wt.% of Er-doping on the critical temperature (T_c) and physical and electrical properties of superconducting YBCO nano-layers. The PLD technique is based on a high-power nanosecond (ns) Nd:YAG laser operating at a 532 nm wavelength, 8 ns pulse duration, 10 Hz repetition rate, and 250 MW as an average power. Adjusting the distance between the target and the substrate affords an occasion to regulate the deposition rate and the particle energy striking the substrate. The substrate heated by a quartz lamp was involved with a mask of stainless steel on a substrate holder. The substrate temperature was checked via a thermocouple during the experiments. We varied the distance between the substrate and target to obtain a high-quality film until we reached the best distance, <i>d</i> = 70 mm. The nano-layer and bulk samples were characterized through a series of measurements such as resistivity, energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and critical temperature T_C. The EDX results have been presented for reporting the chemical composition of the constituent elements. The experimental results revealed that there is a difference in the quality of YBCO material prepared in nano-layer and bulk substances. The images of field emission scanning electron microscopy (FESEM) show that all samples have good homogeneity, especially the 1% Er-doped sample with a less porous structure. After laser ablation treatment, the film starts to have some atomic sequences with a grain size of 100–300 nm under the operation of the tapped mode of atomic force microscope (AFM) scans. The structural properties of the YBCO have hexagonal and cubic polycrystalline structures.
