Compensation temperature of 3d mixed ferro-ferrimagnetic ternary alloy

Compensation Temperature of a Mixed Ising Ferrimagnetic Model in the Presence of External Magnetic Fields

The behavior of the compensation temperature of a mixed Ising ferrimagnetic system on a square lattice in which the two interpenetrating square sublattices have spins σ (±1/2) and spins S (±1, 0) has been studied with Monte Carlo methods. Our model includes nearest and next-nearest neighbor interactions, a crystal field and an external magnetic field. This model is relevant for understanding bi...

Phase diagram for mixed ternary alloy from evolutionary optimization

There is an increasing interest in studying still more complicated magnetic systems. A group of ternary mixed alloys is, among them, a point of interest for as well historical as scientific reasons. The most known material belonging to this group is the famous pigment Prussian blue. The Prussian blue analogues may be characterized by special properties, like the existence of compensation points...

TEMPERATURE AND FIELD DEPENDENT ELECTRICAL CONDUCTIVITY OF AlXGa1-XAs TERNARY ALLOY

The variations of the electrical conductivity with temperature and electric field of the ternary alloy of gallium, aluminium and arsenic (Al0.75Ga0.25As) with atomic compositions of 99/1 and 98/2 have been investigated. The electrical conductivity of the alloy increases with temperature according to the relation, ? = ?0 exp (??/kT). The activation energy calculated from this empirical relation ...

Subpicosecond magnetization reversal across ferrimagnetic compensation points.

Subpicosecond magnetization reversal is experimentally demonstrated by ultrafast heating of a ferrimagnet across its compensation points, under an applied magnetic field. While the reversal is initiated by crossing the magnetization compensation temperature, the short reversal time is related to the angular momentum compensation, where the dynamics of the system is highly accelerated owing to t...
