![]() ![]() In the functionalist perspective, societies are thought to function like organisms, with various social institutions working together like organs to maintain and reproduce them. The functionalist perspective continues to try and explain how societies maintained the stability and internal cohesion necessary to ensure their continued existence over time. Instead, modern societies rely on organic solidarity because of the extensive division of labor, members of society are forced to interact and exchange with one another to provide the things they need. Modern societies however, do not fall apart. Durkheim argued that modern industrial society would destroy the traditional mechanical solidarity that held primitive societies together. ![]() By contrast, he observed that, in modern societies, traditional family bonds are weaker modern societies also exhibit a complex division of labor, where members perform very different daily tasks. Such societies were held together by shared values and common symbols. According to Durkheim, more primitive or traditional societies were held together by mechanical solidarity members of society lived in relatively small and undifferentiated groups, where they shared strong family ties and performed similar daily tasks. He sought to explain social stability through the concept of solidarity, and differentiated between the mechanical solidarity of primitive societies and the organic solidarity of complex modern societies. Durkheim was concerned with the question of how societies maintain internal stability and survive over time. It is sometimes called structural-functionalism because it often focuses on the ways social structures (e.g., social institutions) meet social needs.įunctionalism draws its inspiration from the ideas of Emile Durkheim. The functionalist perspective attempts to explain social institutions as collective means to meet individual and social needs. The insights revealed here not only deepen our understanding of the electronic properties and structural and magnetic ordering transition under high pressure of square lattice antiferromagnets AMoOPO4Cl (A = K, Rb), but also push the boundaries of knowledge by recognizing the role of nonmagnetic ions P 3s in magnetic exchange coupling.\( \newcommand\) The loss of mirror plane symmetry in P4/n phase, makes the P 3s orbitals activate to participate the magnetic interaction, giving rise to competitive ferromagnetic superexchange interaction, in addition to antiferromagnetic direct one, and consequently initiating the magnetic ordering transition. ![]() Furthermore, the mechanism underlined responsible for the magnetic ordering transition at high pressure has been disclosed in terms of density of states and spin density isosurface analysis across the transition. More importantly, the P4/n phase, involving the mutually twisting of MoO5Cl and PO4 polyhedra, satisfactorily reproduces the experimentally observed structural transition and the subsequent magnetic ordering transition from columnar antiferromagnetic ordering to Néel antiferromagnetic one, identified to be the appropriate high pressure structure. Our results indicated that the columnar antiferromagnetic ordering, experimentally determined, is the magnetic ground state of the ambient P4/nmm phase, stabilized by the predominant antiferromagnetic next nearest neighbor interaction J2 in the diagonal directions of square lattice, regardless of the effective Hubbard amendment values. ![]() By means of ab initio density functional theory calculations with taking electronic correlation and van der Waals force into account, we conduct a comprehensive studies of electronic and magnetic properties, as well as structural and magnetic ordering evolution under pressure of the square lattice antiferromagnets AMoOPO4Cl (A = K, Rb) containing Mo5+ ions with, the potential candidates for achieving quantum phases theoretically predicted, existing in the boundary regimes for spin-J1 -J2 square lattice magnets. ![]()
