“…With the constant development of atomic and quantum physics technology fields, solid-state electron spin has become a research focus in quantum sensing. [1,2] Compared with traditional magnetic measurement techniques such as Hall effect sensor, superconducting quantum interference device (SQUID) magnetometry, and magnetic microscope, [3][4][5][6] the method based on the diamond nitrogen-vacancy (NV) color center has exceptional characteristics of sensitivity, volume, power consumption, etc., [7][8][9][10][11] which makes it more extensively applied to weak magnetic measurement technology. [12] It can identify a nanometer-resolved magnetic field at room temperature.…”

A method of detecting the single channel triaxial magnetic field information based on diamond nitrogen-vacancy (NV) color center is introduced. Firstly, the incident angle of the bias magnetic field which can achieve the equal frequency difference optically-detected magnetic resonance (ODMR) spectrum of diamond NV color center is calculated theoretically, and the triaxial magnetic information solution model is also constructed. Secondly, the microwave time-controlled circuit module is designed to generate equal timing and equal frequency difference microwave pulse signals in one channel. Combining with the optical detection magnetic resonance technology, the purpose of sequentially locking and detecting the four formant signals on one side of the diamond NV color center (m s = –1 state signal) is achieved, and the vector magnetic field information detection is accomplished by combining the triaxial magnetic information solution model. The system can obtain magnetic field detection in a range of 0 mT–0.82 mT. The system’s magnetic noise sensitivity is 14.2 nT/Hz1/2, and the deviation angle errors of magnetic field detection θx and θy are 1.3° and 8.2° respectively.

The advantageous applications of magnetic bistable microwires have emerged during long-lasting research. They have a wide range of applications in the scientific sphere or technical practice. They can be used for various applications, including magnetic memories, biomedicine, and sensors. This manuscript is focused on the last-mentioned application of microwires—sensors—discussing various digital signal processing techniques used in practical applications. Thanks to the highly sensitive properties of microwires and their two stable states of magnetization, it is possible to perform precise measurements with less demanding digital processing. The manuscript presents four practical signal-processing methods of microwire response using three different experiments. These experiments are focused on detecting the signal in a simple environment without an external magnetic background, measuring with the external background of a ferromagnetic core, and measuring in harsh conditions with a strong magnetic background. The experiments aim to propose the best method under various conditions, emphasizing the quality and signal processing speed of the microwire signal.

The manufacturing of hybrid materials such as nickel/polyurethane (Ni/PU) hybrid foams and 3D printed hybrid materials with the aid of electrochemical coating of lightweight structures leads to new materials, which can be used as crash absorbers, but also for lightweight design applications. Optimizing the coating quality of the developed hybrid materials necessitates a characterisation on different scales regarding the coating thickness distribution. The ferromagnetic properties of the nickel coating enable a remanent magnetization of the produced hybrid foams and a subsequent measurement of resulting magnetic fields, so that the time‐consumption of a coating distribution determination could be enormously reduced by automating the quantification method. Previous studies have shown, that the local strength of these fields correlate with the deposited mass thus the coating thickness. The here presented automated measurement gives useful information about the homogeneity and the local coating thickness distribution according to an appropriate calibration. In order to optimise the coating quality of the newly developed hybrid materials, improved deposition conditions as well as semi‐automated characterization methods are studied to establish a large‐scale industrial production and a higher applicability of hybrid materials in the near future.This article is protected by copyright.
