Making use of the stress induced magnetic anisotropy in some iron-rich FeCuh'bSiB nanocrystalline materials we studied the thermal dependence of their magnetostriction which becomes zero below the Curie temperature. The choice of a suitable composition and annealing temperature results in materials with zero magnetostriction at room temperature. Due to the low magnetostriction these materials h...

Improved shape of the race-track fluxgate sensor is suggested, which allows precise symetrization of the sensor and thus lower level of the feedthrough signal. The sensor has high untuned sensitivity (16.7 V/T per 1 turn) and low crossfield response thanks to the high shape anisotropy. The closed core and low cross-section guarantee low power consumption, low noise and stable offset. The sensor...

In this paper a novel kind of fluxgate is presented. The sensor is based on helical anisotropy of the ferromagnetic layer, electrodeposited on cupper wire. The saturating field is provided by current flowing in the wire, and the output voltage is measured directly at the terminations of the wire. Therefore no coils are necessary, making possible high miniaturization of the sensor. The effect ha...

Magnetic hysteresis is probably one of the most fascinating and complex physical phenomena. While (dynamically) quasi-linear magnetic materials are the basis of many practical applications (linear inductors, power transformer etc.), there exist several examples wherein the exploitation of non-linear magnetic materials is central to obtaining good signal detection performance. An example of such...

Differential optical detection of a magnetic resonance induced in nitrogen-vacancy (NV) centers in diamond is shown to enable a high-spatial-resolution room-temperature magnetic-field gradiometry on a fiber platform. An ultracompact design of this fiber-based solid-state magnetic gradiometer is achieved by integrating an NV-diamond magnetic sensor with a two-fiber opto-microwave interface, whic...
