Analysis of the spin exchange interactions and the ordered magnetic structures of lithium transition metal phosphates LiMPO4 M Mn Fe Co Ni with the olivine structure
The first is the exchange interaction as a source of magnetic order by which 2D vdW magnetic systems display different exchange interaction mechanisms depending on their crystalline structures

Analysis Of The Spin Exchange Interactions And The Ordered
symmetrybased theoretical analysis In order to analyze the anisotropies measured in FMR and determine the microscopic exchange interactions we begin by writing the most general Hamiltonian allowed by the symmetries of a monolayer with undistorted CrI 6 octahedra the crystal lattice is globally invariant under

useful for intuitive thinking and as a starting point for calculations in ordered states Sec 41 B Besides the spin degrees of freedom a spin model needs a Hamiltonian and the typical terms are surveyed in Sec 41 C Most important is the dotproduct spinspin coupling called an exchange interaction this is the second key physical idea of
The olivinetype compounds LiMPO4 M Mn Fe Co Ni consist of MO4 layers made up of cornersharing MO6 octahedra of highspin M2 ions To gain insight into the magnetic properties of these phosphates their spin exchange interactions were estimated by spin dimer analysis using tight binding calculations and by electronic band structure analysis using first principles density functional
The energymapping analysis based on collinearly ordered spin states allows one to determine the Heisenberg spin exchanges only From the viewpoint of orbital interaction a spin exchange between magnetic ion is none other than the interaction between their magnetic orbitals The latter is caused by the interaction between their porbital
Analysis Of The Spin Exchange Interactions And The Ordered
However the MFT analysis of Culvahouse employed six interactions within each sublattice and 12 interactions between the sublattices on the basis of the work by Long et al who assumed that the strength of a spin exchange interaction between a pair of Fe 3 ions is proportional to the number of Fe OO Fe linkages connecting the two ions
We reviewed briefly how spin dimer electronic band structure and classical spin analyses are employed to describe spin exchange interactions and ordered magnetic structures of magnetic solids It was shown that supersuperexchange interactions are crucial in forming strongly interacting spin units of magnetic solids and hence in determining their magnetic properties and that incommensurate
Over the past two decades the ability to harness spin and exchange interactions has allowed control of singlet and triplet excitons to produce efficient OLEDs as used in smart phone and
The CrVO4type magnetic oxides MMO4 consist of edgesharing MO4 octahedral chains condensed with MO4 tetrahedra and exhibit a wide variety of magnetic structures The magnetic properties of these oxides were examined by studying their spin exchange interactions on the basis of spin dimer analysis The nature and magnitudes of the intra and interchain spin exchange interactions depend on
