Magnetic phase diagram of the S=1/2 triangular layered compound NaNiO2: a single crystal study [PDF]

, 2010
Using magnetic torque measurement on a NaNiO2 single crystal, we have established the magnetic phase diagram of this triangular compound. It presents 5 different phases depending on the temperature (4 K - 300 K) and magnetic field (0 - 22 T) revealing ...

Compact optical pumping system based on offaxis freeform mirror collimation for miniaturized atomic gyroscopes [PDF]

EPJ Web of Conferences
Conventional optical systems for laser beam expansion, collimation, and reflective path configurations in miniaturized atomic gyroscopes face challenges due to excessive volume and component complexity, limiting further optical integration.

Magnetic measurement system for high-field magnets

Journal of Synchrotron Radiation, 1998
One of the main principles in electrodynamics, the change of magnetic field flux inducing an EMF in a wire coil, is applied for magnetic measurement. A scheme and the main parameters of the magnetic measurement system are described. The system was successfully used for magnetic measurement of a 7 T superconducting wiggler for LSU CAMD; results are ...

Nonresonant microwave absorption in epitaxial La-Sr-Mn-O films and its relation to colossal magnetoresistance [PDF]

, 2007
We study magnetic-field-dependent nonresonant microwave absorption and dispersion in thin La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ films and show that it originates from the colossal magnetoresistance.

Efficient magnetic field measurements

2017 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2017
Measuring magnetic fields of equipment under test at low frequencies which is received by loop antennas using an EMI receiver with small bandwidths takes much time and can even reach a week for a standard measurement. This waste in time could be avoided by applying time domain measurements.

Measurement System for Short-Pulsed Magnetic Fields

Sensors, 2023
A measurement system based on the colossal magnetoresistance CMR-B-scalar sensor was developed for the measurement of short-duration high-amplitude magnetic fields. The system consists of a magnetic field sensor made from thin nanostructured manganite film with minimized memory effect, and a magnetic field recording module. The memory effect of the La1−

Direct high-precision measurement of the magnetic moment of the proton

, 2014
The spin-magnetic moment of the proton $\mu_p$ is a fundamental property of this particle. So far $\mu_p$ has only been measured indirectly, analysing the spectrum of an atomic hydrogen maser in a magnetic field. Here, we report the direct high-precision

Measurement of the Cotton Mouton effect of water vapour

, 2013
In this paper we report on a measurement of the Cotton Mouton effect of water vapour. Measurement performed at room temperature ($T=301$ K) with a wavelength of 1064 nm gave the value $\Delta n_u = (6.67 \pm 0.45) \cdot 10^{-15}$ for the unit magnetic ...
