A Monte Carlo simulation of the Ising Model, a simplified model for studying the behavior of magnetic materials at various temperatures, was constructed. This model illustrated the transition between magnetic and non-magnetic phases as temperature is increased, and showed critical-point behavior at the transition. A general system for studying the behavior of many different configurations of pa...

objective(s) physiological changes in the body may be utilized as potential triggers for controlled drug delivery. based on these mechanisms, stimulus-responsive drug delivery has been developed. materials and methods in this study, a kind of poly (n-isopropylacrylamide-acrylamide) membrane was prepared by radical copolymerization. changes in swelling ratios and diameters of the membrane were i...

We study the classical XY (plane rotator) model at the KosterlitzThouless phase transition. We simulate the model using the single cluster algorithm on square lattices of a linear size up to L = 2048. We derive the finite size behaviour of the second moment correlation length over the lattice size ξ2nd/L at the transition temperature. This new prediction and the analogous one for the helicity m...

A new one-dimensional (1-D) ion-pair compound, [1,7-bis(1-methylimidazolium)heptane][Ni(mnt)(2)](2) (mnt(2-) = maleonitriledithiolate), was synthesized and characterized structurally and magnetically. This compound shows a spin-Peierls-type transition at around 235 K. Its crystal structure belongs to the monoclinic system with space group C2/c and the magnetic [Ni(mnt)(2)](-) anions form unifor...

The electroweak phase transition in the magnetic and hypermagnetic fields is studied in the Standard Model on the base of investigation of symmetry behaviour within the consistent effective potential of the scalar and magnetic fields at finite temperature. It includes the one-loop and daisy diagram contributions. All discovered fundamental fermions and bosons are taken into consideration with t...

We have studied the [100]-[110] anisotropy of the Compton profile in the bilayer manganite. Quantitative agreement is found between theory and experiment with respect to the anisotropy in the two metallic phases (i.e., the low temperature ferromagnetic and the colossal magnetoresistant phase under a magnetic field of 7 T). Robust signatures of the metal-insulator transition are identified in th...

First-principles calculations have been carried out to study the structural, electric, and magnetic properties of Ni3TeO6-type A2FeMoO6 compounds (A = Sc, Lu). Their electric and magnetic properties behave like room-temperature ferrielectric and ferrimagnetic insulators where polarization comes from the un-cancelled antiparallel dipoles of (A(1), Fe(3+)) and (A(2), Mo(3+)) ion groups, and magne...

Neutron diffraction measurements on a single crystal of CeGe1.76 reveal a complex series of magnetic transitions at low temperature. At TN≈7 K, there is a transition from a paramagnetic state at higher temperature to an incommensurate magnetic structure characterized by a magnetic propagation vector (0 0 τ) with τ≈14 and the magnetic moment along the a axis of the orthorhombic unit cell. Below ...
