Following our previous work on the magnetocaloric compounds FeMnAsxP[Formula: see text], we obtain thermomagnetic properties for the barocaloric antiperovskite Mn3GaN, which has been investigated in recent years in view of its thermal response under

A wealth of experimental and theoretical data on the crystallographic and magnetic properties of the magnetocaloric compounds MnFeAs x P1 − x (0.25 ≤ x ≤ 0.65) and MnFeAs has become available in the last decade. By analyzing the data and treati

The present paper is based upon the fact that if an object is part of a highly stable oscillating system, it is possible to obtain an extremely precise measure for its mass in terms of the energy trapped in the system, rather than through a ratio bet

A simple phenomenological model is developed, which indicates the existence of a direct link between the concept of rest mass of a particle and magnetodynamic energies associated to the formation of the particle. The model is based upon the principle

There has been an increasing technological interest on magnetic thin films containing antidot arrays of hexagonal or square symmetry. Part of this interest is related to the possibility of domain formation and pinning at the antidots boundaries. In t

Nanosphere lithography is a simple and accessible technique for nanostructuring of materials. Combined with electrodeposition, it allows the production of compact, ordered antidot networks. In contrast to other lithographic techniques, the resulting

Introductory electromagnetism courses usually start the exposition of Faraday's induction law discussing the ordinary situation in which the induced electromotive force arises due to the motion of a resistive circuit in the presence of a magnetic fie

We discuss theoretically the properties of an electromechanical oscillating system whose operation is based upon the cyclic conservative conversion between gravitational potential, kinetic and magnetic energies. The system consists of a superconducti

Cu, Fe, Gd and Nd dopants were added to HNb2O5 in a range of concentrations to investigate the influence on the magnetic properties. The dopants fill the vacant sites in the channels along the b axis of the structure. Magnetic moments tend to remain

H-Nb2 O5 (Nb28 O70 ) is a semiconductor whose structure is built of NbO6 octahedra, which share corners and edges to form blocks parallel to the basal ac plane of the structure. One unit cell contains two blocks of 3 × 4 and 3 × 5 octahedra displac
