Ultrahigh-field hole cyclotron resonance absorption in In1−xMnxAs films

We have carried out an ultrahigh-field cyclotron resonance (CR) study of p-type In1−xMnxAs films, with Mn composition x ranging from 0 to 2.5%, grown on GaAs by low-temperature molecular-beam epitaxy. Pulsed magnetic fields up to 500 T were used to make cyclotron resonance observable in these low-mobility samples. Clear CR spectra have been observed for all the samples at high fields in the meg...

Mapping with Ultrahigh Field Magnetic Resonance: Physics and Frontier Applications

Cardiovascular magnetic resonance imaging (CMR) has become an indispensable clinical tool for the assessment of morphology, function and structure of the heart muscle. By exploiting quantification of the effective transverse relaxation time (T2 ) CMR also affords myocardial tissue characterization and probing of cardiac physiology, both being in the focus of ongoing research. These developments...
