The major technical difficulty of MR spectroscopy is obtaining a homogeneous magnetic field. Indeed, the accuracy of the MR spectra is directly dependent of the magnetic field homogeneity, the ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

Tiny magnetic "flowers" engineered by physicist Anna Palau are redefining how we manipulate magnetic fields. These ...

A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, ...

BESSY II: Magnetic 'microflowers' enhance local magnetic fields A metamaterial with potential applications in sensor technology Date: March 25, 2025 Source: Helmholtz-Zentrum Berlin für ...

NASA has been monitoring a strange anomaly in Earth's magnetic field: a giant region of lower magnetic intensity in the skies ...

A material’s response to an applied magnetic field can be characterized as diamagnetic, paramagnetic, ferromagnetic or antiferromagnetic. Although molecular qubits offer precise, controllable ...

An open-transmit and 24-channel flexible receiver head coil enhances ultrahigh-field fMRI, enabling sub-millimeter resolution for somatosensory and motor cortex mapping, advancing neuroscience and ...

Mar. 25, 2025 — To get around the constraints of quantum physics, researchers have built a new acoustic system to study the way the minuscule atoms of condensed matter talk together. They hope ...

Abstract: Expressions for the total power flow from a vertical oscillating magnetic dipole and a horizontal electric dipole are employed to determine the input resistances of both types of antennas ...
