Magnetic fields couple most strongly to the electrons in a material, either by acting on electrical currents generated by the electrons’ quantum mechanical motion, or by coupling to the magnetic moments arising from the electrons’ intrinsic spin. 39 Non universal Ising-like transition in two-dimensional XY spin. systems induced by external magnetic field.

    Figure 6(a) shows the soft magnetic layer (Fe/(disordered FePt)) thickness effect on the out-of-plane coercivity field of Fe/FePt/FePtAg composite films. The coercivity is reduced from kOe to kOe for FePtAg film and Fe/FePt(7 nm)/FePtAg composite film, respectively. The coercivity field is reduced drastically by a factor of 2 when the total thickness of Fe(2 nm)/FePt(7 nm) Cited by: 3.

Magnetic ordering in thin Ising bilayer systems by Donna G McKenzie Download PDF EPUB FB2

Magnetism in two-dimensional materials is not only of fundamental scientific interest but also a promising candidate for numerous applications. However, studies so far, especially the experimental ones, have been mostly limited to the magnetism arising from defects, vacancies, edges, or chemical dopants which are all extrinsic effects.

Here, we report on the observation Cited by: 5 dichalcogenides,15 In magnetic crystals, low energy excitations such as two magnon scattering appears in the Raman spectrum, 16 or some of the Raman peak positions or intensities change when spins are ordered,18 Since direct measurement of the magnetic properties of atomically thin magnetic materials is difficult, especially in the case of antiferromagnetism, the.

In order to study the dynamic magnetic features of the mixed spin-1 and spin-5/2 Ising system, we have used the mean-field theory (MFT) based on the Glauber-type stochastic dynamics on the bilayer square lattice (BSL).

By employing the Master equation, dynamic equations describing the behavior of the system are derived. The average order parameters Cited by: 2. Request PDF | Phase Transition in a Spin-1/2 and Spin-1 Ising Bilayer Film with Non-magnetic Inter-layers | The phase transition, phase diagrams.

Our discovery is particularly signi cant in the context of the e ort to cre-ate bilayer exciton systems at a nite density.

Stripes and other complex ordering phenomena in the nite density electron systems are believed to be driven by. The rst aim is subsidiary to the second purpose: to create a model for a bilayer system at t= 1 with an in-plane magnetic eld B k.

Apart from the above-mentioned experimental ndings, in-plane magnetic elds are often used to suppress tunnelling between the layers, 5. Chapter 1.

A large number of the publications on gadolinium and its magnetic behavior in. dered ultrathin magnetic bilayers dramatically depends on the transport regime. When the disorder is strong and the transport is diffusive, the spin Hall effect dominates, leading to a damping torque that agrees with the widely FIG.

This suggests that, fundamentally, an assembly of loop-like structures, in which current can flow and create a small magnetic dipole, might work as an artificial magnetic material.

Systems and methods for providing thermal barrier bilayers for heat assisted magnetic recording (HAMR) media are provided.

One such HAMR medium includes a substrate, a heat sink layer on the substrate, a thermal barrier bilayer on the heat sink layer, the bilayer comprising a first thermal barrier layer on the heat sink layer and an amorphous underlayer on the first thermal barrier Cited by: Exchange bias or exchange anisotropy occurs in bilayers (or multilayers) of magnetic materials where the hard magnetization behavior of an antiferromagnetic thin film causes a shift in the soft magnetization curve of a ferromagnetic film.

The exchange bias phenomenon is of tremendous utility in magnetic recording, where it is used to pin the state of the readback heads of hard. Coercivity, also called the magnetic coercivity, coercive field or coercive force, is a measure of the ability of a ferromagnetic material to withstand an external magnetic field without becoming analogous property in electrical engineering and materials science, electric coercivity, is the ability of a ferroelectric material to withstand an external electric field without.
