Search for Axionlike Dark Matter Using Solid-State Nuclear Magnetic Resonance. [PDF]

Physical Review Letters, 2021
We report the results of an experimental search for ultralight axionlike dark matter in the mass range 162-166 neV. The detection scheme of our Cosmic Axion Spin Precession Experiment is based on a precision measurement of ^{207}Pb solid-state nuclear ...

An ultrabroadband metamaterial absorber based on remarkable magnetic coupling via constructing conductive composite resonators and magnetic gradient gyroid structure

Virtual and Physical Prototyping, 2023
Broadband electromagnetic absorbing is still a challenge due to the huge difference of waves properties in different frequency bands. Herein, based on the transmission-line theory, we propose an in-plane hybrid metamaterial absorber using coupled ...

Link Coupling for Nuclear Magnetic Resonance [PDF]

Review of Scientific Instruments, 1954
In an attempt to use proton magnetic resonance for regulation of magnetic fields of 10 kilogauss or more, it has been found that the conventional probe sample holder used by other investigators (1) gave inadequate, if any, resonance lines above 40 mc/sec. In such arrangements, the oscillator tank coil is at the end of a coaxial probe. The weaker lines

Temperature and magnetic field dependence of a Kondo system in the weak coupling regime [PDF]

, 2013
The Kondo effect arises due to the interaction between a localized spin and the electrons of a surrounding host. Studies of individual magnetic impurities by scanning tunneling spectroscopy have renewed interest in Kondo physics; however, a quantitative ...
