Magneto-optical Faraday effects were used to observe the evolution of the ion-irradiated sample in longitudinal and perpendicular magnetic fields. The ferromagnetic phase of the initial in-plane anisotropic fcc β-Co phase transformation to β-Co (N) phase was terminated at paramagnetic CoN x phase.
Space radiation is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light – eventually, only the nucleus of the atom remains. Space radiation is made up of three kinds of radiation: particles trapped in the Earth's magnetic field; particles shot ...
Life on Earth is protected from the full impact of solar and cosmic radiation by the magnetic fields that surround the Earth and by the Earth's atmosphere. The Earth also has radiation belts caused by its magnetic field.
The domain wall velocities driven by out-of-plane magnetic fields up to 200 mT are reported in Fig. 1 for the samples in the pristine state and after irradiation. As it can be observed, the strongest trend is a shift of the curves toward low field values with increasing irradiation fluence.
As an example, consider a sample of water in a 2.3487 T external magnetic field, irradiated by 100 MHz radiation. If the magnetic field is smoothly increased to 2.3488 T, the hydrogen nuclei of the water molecules will at some point absorb rf energy and a resonance signal will appear.
Earth's magnetic field protects life on our blue planet — and astronomers just found evidence of a magnetic field on a rocky exoplanet 12 light-years away. (opens in new tab) Comments (0)
We focus on one such phenomenon, which is the ability of a laser-irradiated magnetized plasma to amplify a seed magnetic field. We performed a series of fully kinetic 3D simulations of magnetic field amplification by a picosecond-scale relativistic laser pulse of intensity 4.2 × 10 18 W cm −2 incident on a thin overdense target.
In this study, we evaluated the impact of a 1.5 T magnetic field on radiation-induced lung damage in C57L/J mice. We irradiated 140 mice to the whole thorax with …

In this work, acting solely on the magnetic degree of freedom, we reveal an anomalous feature in the electronic transport of V2O3: On cooling, the magnetoresistance changes from positive to negative values well above the MIT temperature, and shows divergent behavior at the transition.
The results of this study show that the effects produced by the alternating mag- netic field applied pre-sowing depend on genotype and combination of irradiation parameters: magnetic flux density and irradiation time. …

Likewise, the hyperfine magnetic field of the regular B2 Fe atoms was found to be H 0 = 27.135(2) ... the same holds true for re-annealing the completely non-magnetic irradiated sample.

Abstract In this paper, we show that magnetic skyrmion nucleation can be controlled using Ga + ion irradiation, which manipulates the magnetic interface effects (in particular, the magnetic anisotropy and Dzyaloshinskii-Moriya interaction) that govern the stability and energy cost of skyrmions in thin-film systems.

Significant improvement of magnetization is achieved in irradiated Ni 41 Mn 43 Co 6 Sn 10 alloy. • A large magnetostrain of 0.22% is obtained under a low magnetic field of 4 T. Abstract Promising magnetostrain effect endows the Ni- (Co)-Mn-X (X = Sn, In, Sb) based Heusler alloys large potential for the application on intelligent-drive field.
In addition, the MDT shields both habitat and magnets eliminating the secondary particle irradiation hazard, which can dominate over the primary GCR for the closed magnetic topologies that have …

The dose of cosmic radiation increases as the magnetic field strength drops and returns to lower levels as the magnetic field reestablishes itself. The question is, how high will the cosmic radiation …
In the case of cosmic radiation, the Earth's magnetic field deflects lower-energy cosmic rays around the Earth, forming a "bubble" around our planet. higher-energy cosmic rays still penetrate the …

Under a magnetic field, sublattice B does not develop its full moment due to the frustration from the magnetic field. The difference in spin ordering is depicted at the bottom of (c),(d).
However, photoelectrochemical materials with a ferromagnetic field are scarce, and the internal magnetic field is negligible in nonferromagnetic materials. To address this issue, we propose a rational method for preparing ferromagnetic TiO 2 powder using controllable oxygen vacancies in anatase TiO 2 with co-exposed {001} and {101} …
