Ferrites, combining insulating and ferrimagnetic properties, have long been used in technology. The aim of this paper is to focus on new features in these materials. In the classical theory of ferrimagnets, N茅el had predicted the unusual thermal variation of the spontaneous magnetization, such ...
Among them are such things as heat sensors and motion detectors that are commonly used in fire safety and security systems. Even the automobile industry benefits from employing the physics of ferroelectricity, with some fuel injectors on diesel engines utilizing ferroelectricity in order to control ...
In ferrites the magnetic moments of constituent atoms align themselves in two or three different directions. Apartial cancellation of the magnetic field results, and the ferrite is left with an overall magnetic field that is less strong than that of a ferromagnetic material. What is a coercive fi...
Diamagnetism: All materials displaydiamagnetism, which is the tendency to be repelled by a magnetic field. However, other types of magnetism can be stronger than diamagnetism, so it is only observed in materials that contain no unpaired electrons. When electrons pairs are present, their "spin" m...
Scientists are also exploring modern materials like quantum dots by sequentially analyzing their linear and nonlinear properties, as detailed in a recent article inPhysics Letters A.11 As research advances, a combined understanding of LO and NLO remains crucial for pushing technological boundaries and ...
In the 1950s a new group of magnets was developed. Hard hexagonal ferrites, also called ceramic magnets, can be cut into thinner slices and be exposed to low level demagnetizing fields without losing their magnetic properties. They also are cheap to make. The molecular hexagonal ferrite structure...
in Material Science from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) in Bangalore, where she used Raman spectroscopy to study phase transitions in various novel materials. Her research involved chalcogenides, orthoferrites, vanthoffites, eutectics, and metal-organic frameworks, ...
