The temperature of the transition to the polar state in ferroelectric composites, representing spherical ferroelectric inclusions embedded in a dielectric matrix, under a depolarizing field effect is investigated. This temperature is determined both in the absence and presence of screening effects of the depolarizing field of the bound charges of spontaneous polarization at the inclusions surfa...

We report the preparation, crystallization, and solid-state characterization of the first member of a new family of tris(1,9-disubstituted phenalenyl)silicon neutral radicals. In the solid state, the radical packs as weak partial pi-dimers with intermolecular carbon...carbon contacts that fall at the van der Waals atomic separation. Magnetic susceptibility measurements indicate approximately 0....

Three N-salicylideneamine derivatives bearing TEMPO (2,2,6,6-tetra- methyl-1-piperidinyloxy) substituents were prepared in order to study their structure and property relationships and to investigate the possibilities of the existence of heat and/or light responsive magnetic properties. Curie-Weiss behavior with weak ferromagnetic intermolecular spin-spin interactions was observed in one of the...

The sputter deposited ~Pt/Co/Pt/Ni! multilayer films were studied as possible alternative low Curie temperature multilayers for magneto-optical recording. The Curie temperatures of these multilayers were found to be between 150 and 300 °C, which are much lower than those of Co/Pt multilayers or ~Co,Ni!/Pt multilayers. The coercivities of these multilayers were between 450 and 800 Oe. The Kerr s...

The (15)N-HSQC spectra of low-spin cyano-met-myoglobin and high-spin fluoro-met-myoglobin were assigned and dipole-dipole-Curie-spin cross-correlated relaxation rates measured. These cross-correlation rates originating from the dipolar (1)H-(15)N interaction and the dipolar interaction between the (1)H and the Curie spin of the paramagnetic center contain long-range angular information about th...

This review aims to commemorate the life, and the accomplishments of Pierre and Marie Curie in Physics and in Medicine. Although they are primarily known for their discoveries of the elements of radium and polonium, which took place two years after the discovery of radioactivity by Henry Becquerel, Pierre's discovery of the piezo-electric phenomenon, his research on crystal symmetry, magnetism ...

Emerging for future spintronic/electronic applications, magnetic semiconductors have stimulated intense interest due to their promises for new functionalities and device concepts. So far, the so-called diluted magnetic semiconductors attract many attentions, yet it remains challenging to increase their Curie temperatures above room temperature, particularly those based on III-V semiconductors. ...
