First-principles calculations to investigate magnetic, electronic, mechanical and dynamical properties of the bimetallic M-Pt (M: Mn Co and Ni) alloys

N. L. Lethole et al.

Summary: This study investigates the properties of L10 ordered M-Pt (M = Mn, Co and Ni) bimetallic alloys, including magnetic, electronic, mechanical and dynamical characteristics. First-principles calculations based on the Density Functional Theory (DFT) method and Generalized Gradient Approximation (GGA) functional were employed using the CASTEP simulation code. The results show that MnPt and NiPt alloys are stable at 0 K, while CoPt is metastable, consistent with experimental phase stability diagrams. The MnPt alloy exhibits higher magnetic properties compared to CoPt and NiPt, with magnetic spin values of 4.04 mu B, 2.52 mu B and 0.98 mu B, respectively. The MnPt and NiPt alloys are predicted to be mechanically and dynamically stable at ambient conditions, while CoPt is stable above 13 GPa. Additionally, all M-Pt systems exhibit strong uniaxial magneto-crystalline anisotropy, making them desirable for spintronic and magnetic recording devices.

Influence of oxygen and nitrogen doping on the structure and magnetic properties of CoNi alloy: First principle calculations

Abdalla Obeidat et al.

Summary: In this study, we investigated the effects of oxygen and nitrogen doping on the magnetic properties of CoNi alloy using density functional theory. Our calculations revealed that CoNi:ONi alloy exhibited enhanced saturation magnetization and slightly reduced magnetic crystalline anisotropy, while CoNi:OCo alloy showed a small reduction in both parameters. On the other hand, CoNi:NCo and CoNi:NNi alloys consistently exhibited reductions in saturation magnetization and magnetic crystalline anisotropy. Therefore, CoNi:ONi alloy could be suitable for permanent magnets.

Influence of oxygen and nitrogen doping on the structure and magnetic properties of FePt alloy: First principles calculations

Abdalla Obeidat et al.

Summary: We studied the magnetic and electronic properties of L10-FePt alloy interstitial doped by oxygen or nitrogen using tetragonal distortion. The density functional theory from first principle was applied, and the generalized gradient approximation (GGA) of Perdew-Burke-Ernzerhof (PBE) was used. We found that the magnetocrystalline anisotropy (MCA) significantly increased for FePt:NPt, reaching a value of 3.879 meV, exceeding the pristine value. The anisotropy field (Ha), saturation magnetization (Ms), and the energy product (BH)max were close to the pristine value, and these parameters can be tuned for practical applications.

Magnetic properties of transition-metal atomic monolayer in nickel supercell: Density functional theory and Monte Carlo simulation

Khaled Aledealat et al.

Summary: The magnetic properties of 3d, 4d, and 5d transition-metal atomic mono-layers sandwiched in pure nickel were studied using DFT and MC methods. It was found that these transition metals can modify the magnetic properties of nickel, and the perpendicular and in-plane magnetocrystalline anisotropy energies show variations. The substitution effect of TM monolayers on exchange interactions extends to the third layer, and the Curie temperature changes depending on the TM and sandwich structure.

First-principles study of electronic structure and magnetic properties of L10-ordered FeNi, FePd, and FePt alloys

K. Aledealat et al.

Summary: The structural, electronic, and magnetic properties of L10-ordered FeM alloys (M = Ni, Pd, or Pt) were studied using first-principles method, revealing that the PBE approximation has the most accurate results for lattice parameters and that the most stable spin configuration is ferromagnetic. FePd and FePt alloys can transition from ferromagnetic to antiferromagnetic state by varying the tetragonality ratio, leading to the observation of a pseudogap. Large magnetocrystalline anisotropies were found in FePt alloy, while FePd and FeNi showed relatively lower values. Additionally, Heisenberg exchange interactions were calculated from first-principles and Green's functions formalism.

Dmitry M. Korotin et al.

Summary: The electronic and magnetic structure of the novel cuprate Cu2F5 was explored using DFT+U calculation, revealing a unique 2D-magnetism with strong anisotropy of exchange interaction. A very stable antiferromagnetic ordering was found, where the in-plane magnetic interaction is much stronger than the interplane interaction.
