Effect of amifostine, a radiation-protecting drug, on muscle tissue partial pressure of oxygen was investigated by electron paramagnetic resonance spectroscopy and imaging. When amifostine was administered intraperitoneally or intravenously to mice, the linewidth of the electron paramagnetic resonance spectra of the lithium octa-n-butoxy-substituted naphthalocyanine implanted in the mouse leg m...

Abstract Magnetic properties are universal and inherent in all matter. While most experimental approaches focus on ferromagnetism electromagnetism, few experiments exist to analyse diamagnetism paramagnetism. To demonstrate these mostly unknown types of magnetic, magnetic balance represent a simple compelling approach. However, phenomenological not sufficient develop fundamental understanding m...

Magnetic Measurements In article number 2300927, Qiang Li, Yanglong Hou, and co-workers discuss the ways in which magnetic techniques (represented image by ancient Chinese Magnet Sinan), including nuclear resonance, electron paramagnetic magnetometry Mössbauer spectroscopy, can help development of energy science battery). Based on properties materials, measurements characterize multi-angle info...

Paramagnetic metal ions with fast-relaxing electronic spin and anisotropic susceptibility tensor provide a rich source of structural information that can be derived from pseudo-contact shifts, residual dipolar couplings, dipole-dipole Curie spin cross-correlation, and paramagnetic relaxation enhancements. The present study draws attention to a cross-correlation effect between nuclear relaxation...

UNLABELLED The adequacy of cerebral tissue oxygenation (PtO(2)) is a central therapeutic end point in critically ill and anesthetized patients. Clinically, PtO(2) is currently measured indirectly, based on measurements of cerebrovascular oxygenation using near infrared spectroscopy and experimentally, using positron emission tomographic scanning. Recent developments in electron paramagnetic res...

We have observed a distinct surface phase transition for an important class of colossal magnetoresistive materials, La0.65D0.35MnO3 (with D = Sr, Pb) occurring in a surface layer compositionally different from the bulk. The surface phase transition occurs around 240 K compared to 350 K for the bulk and is fundamentally different. In the bulk, a ferromagnetic metal to paramagnetic ‘bad metal’ oc...

We report transverse field muon spin rotation studies of the rare earth pyrochlores Gd2Ti2O7 and Tb2Ti2O7: The paramagnetic shift in the observed precession frequency depends on the local spin susceptibility and probes the contact hyperfine and dipolar fields at the muon site within these materials. The results are compared with measurements of the bulk susceptibility. While no features associa...

On the basis of an ab initio theory of metallic magnetism in layered materials, we investigate the onset of magnetic order in thin (2-8 layers) fcc-Fe films on and embedded in Cu(100) substrates. In particular, we find an oscillatory dependence of the Curie temperatures on embedding depth, in excellent agreement with experimental data. The thermally induced spin fluctuations are treated within ...

We present an experimental realization of a magnetic two-dimensional XY system using amorphous materials. The classification of the dimensionality is based on the critical behavior of amorphous Co68Fe24Zr8(d)/Al70O30 (20Å) multilayers, where d = 11 − 16Å. Analysis of the remanent magnetization, the magnetic isotherms, the initial susceptibility, and the magnetic correlation length shows that th...
