MAGNETIC PHASE DIAGRAM IN THE FERRIMAGNETIC SPIN GLASS SYSTEM SrCr8Fe4-xGaxO19

چکیده
We report here on low field dc and ac magnetic susceptibility measurements on the compounds SrCreFeq-,GaXOlg with x = 0 to x = 4. We have determined their magnetic phase diagram and proved that increasing the Ga content in the structure we cross from fernmagnetic-like ordering and spin glass reentrance t o pure spin glass behaviour and finally to the disapearance of any magnetic ordering in SrCr8Ga,019 as a consequence of the reduced lattice dimensionality.

Magnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...
متن کاملMacroscopic phase diagram and magnetocaloric study of metamagnetic transitions in the spin chain system Ca3Co2O6
The magnetic entropy change ( SM) in a single crystal of the geometrically frustrated spin chain system Ca3Co2O6 has been determined under the influence of a wide range of temperatures and magnetic field variations. Our findings are consistent with the spin-density wave description of the zero field order, and with the suppression of the modulated state at low field. Metamagnetic transitions to...

We theoretically demonstrate the interplay of uniform spin-orbit coupling and uniform Zeeman magnetic field on the topological properties of one-dimensional double well nano wire which is known as Su-Schrieffer-Heeger (SSH) model. The system in the absence of Zeeman magnetic field and presence of uniform spin-orbit coupling exhibits topologically trivial/non–trivial insulator depending on the h...

In this study, the effect of four-spin exchanges between the nearest and next nearest neighbor spins of honeycomb lattice on the phase diagram of S=3/2 antiferomagnetic Heisenberg model is considered with two-spin exchanges between the nearest and next nearest neighbor spins. Firstly, the method is investigated with classical phase diagram. In classical phase diagram, in addition to Neel order,...
متن کاملPhase diagrams in the Blume-Emery-Griffiths Ising thin films
We study the spin-1 Ising model with bilinear and biquadratic exchange interactions and single-ion crystal field. In addition to the four usual phases: disordered DIS, ferromagnetic FER, antiquadrupolar AQU and ferrimagnetic FRI, we found three new phases in the case of a thin magnetic film, namely: the sublattice A non magnetic phase NMA, the sublattice B non magnetic phase NMB and the global ...
