Strain fields and critical phenomena in manganites I: spin-lattice Hamiltonians
نویسندگان
چکیده
We use a model Hamiltonian to study critical phenomena in manganites. This includes long-range strain interactions, and coupling between the magnetic order parameter field. perform perturbative renormalization group (RG) analysis calculate static exponents, correct one-loop level. compare our RG results with many experiments on doped manganite systems. Our theory is excellent agreement experimental values for exponents.

Monte Carlo studies of critical phenomena in mixed spin-3/2 and spin-5/2 Ising model on square lattice
We used a Monte Carlo simulation to analize the magnetic behavior of Ising model of mixed spins S i = ±3/2,±1/2 and σ j = ±5/2,±3/2,±1/2, on a square lattice. Were studied the possible critical phenomena that may emerge in the region around the multiphase point (D/|J1| = −3, J2/|J1| = 1) and the dependence of the phase diagrams with the intensities of the anisotropy field of single ion (D/|J1|)...
متن کاملCRITICAL PHENOMENA OF ANISOTROPIC SPIN GLASS ZnMn
Longitudinal (11 c) and transverse (LC) nonlinear susceptibilities have been measured on the Ising-type ZnMn spin glass. The critical exponents obtained from the scaling hypothesis depend on the anisotropy/exchange ratio, which can suggest a crossover effect from Heisenberg to Ising spin glasses in real RKKY systems. Critical behaviors of the nonlinear susceptibility in spin glasses have been e...
متن کاملSpin excitations in ferromagnetic manganites
An effective one–band Hamiltonian for colossal–magnetoresistance (CMR) manganites is constructed and the spin excitations are determined. Fitting the experimental data by the derived spin–wave dispersion gives an eg–electron hopping amplitude of about 0.2 eV in agreement with LDA band calculations.
متن کاملCritical phenomena in neutron stars: I
We consider the evolution in full general relativity of a family of linearly unstable isolated spherical neutron stars under the effects of very small perturbations as induced by the truncation error. Using a simple idealfluid equation of state, we find that this system exhibits a type I critical behaviour, thus confirming the conclusions reached by Liebling et al (2010 arXiv:1001.0575v1) for r...
متن کاملRandom matrix theory and critical phenomena in quantum spin chains.
We compute critical properties of a general class of quantum spin chains which are quadratic in the Fermi operators and can be solved exactly under certain symmetry constraints related to the classical compact groups U(N),O(N), and Sp(2N). In particular we calculate critical exponents s,ν, and z, corresponding to the energy gap, correlation length, and dynamic exponent, respectively. We also co...
