The factor Δ = ΔE/kBT is called the thermal stability factor and defines the data retention time of magnetic memories. Storage duration depends on material properties and the nanostructure size, particularly the volume of the magnetic storage layer. Furthermore, as chip storage capacity increases...
Magnetic fluids, suspensions of magnetic particles in carrier liquids like water, oil or organic solvents, combine magnetic properties with fluidity to achieve features such as rapid magnetic response, reversible viscosity, and tunable thermal and optical properties. However, these carriers tend to have...
For over 100 years, the group-theoretic characterization of crystalline solids has provided the foundational language for diverse problems in physics and chemistry. However, the group theory of crystals with commensurate magnetic order has remained incom
The magnetic properties of the nickelates differ substantially from those of the cuprates in that the pristine undoped cuprates exhibit commensurate AFM order. In sharp contrast, no long-range AFM order is found inRNiO233,34,35,36, despite the existence of robust two-dimensional (2D) AFM spi...
However, most advanced magnetic materials are based on intermetallic compounds with complex crystalline and electronic structures where electronic interactions often govern the magnetic properties. Section “Intermetallic Compounds of d-d and d-p Types” introduces the d-d and d-p intermetallic compounds...
Ab initio calculations have been performed to obtain the most stable structure for each of the three binary systems. In addition, the optical and electrical properties such as electronic band structure, density of states and partial density of states of MxPt1-x binary alloys have been investigated...
The magnetic properties of the samples are shown in Figure 1B. The magnetic hysteresis loop showed no remanence or coercivity at room temperature, thus suggesting that the particles had superparamagnetic character, such that no magnetization remained when the applied magnetic field was removed. The ...
The values of coercivity (Hc), the maximum corresponding magnetizations due to the applied field of 18 kOe (σ18), specific residual magnetization (σr), and the value of the ratio σr/σ18 are given in Table 4. Table 4. Magnetic hysteresis properties of SrFe12-xNdxO19 (0 ≤ x≤ 0....
Based on the obtained results, it was found that the magnetic induction value changes the properties of composites. This therefore acts as one method of receiving new alternative materials, the degradation of which in the environment would take far less time. Keywords: polymers; biopolymers; ...
But it is not clear that the physical properties of aragonite differ all that much from those of calcite. Permanent magnets and alternating electromagnetic fields Most of the permanent magnet devices employ a sequence of magnets, arranged so that the water passes alternately through magnetized and ...
