Demonstrating voice transmission based on analog and digital phase modulation of spin torque nano-oscillators
Spin torque nano-oscillators (STNO) are nanoscale devices with wide band frequency tunability. Their multifunctional RF properties are well suited to define novel schemes for wireless communications that use basic protocols for data transmission such as amplitude, frequency and phase shift keying (ASK, FSK, PSK). In contrast to ASK and FSK, implementation of PSK is more […]

A generic probe for spin fluctuations in nanometer-scale films
In the field of spintronics, which relies on the spin-dependent transport properties of matter, exploring spin fluctuations and phase transitions in ultrathin films is essential as it provides key information to engineer materials for applications. Here, O. Gladii et al investigated the generic character of a novel method to probe spin fluctuations through demonstration with […]
Read moreImpact of heating on the stability phase diagrams of perpendicular MTJs
Measured switching diagrams of perpendicular magnetic tunnel junctions exhibit unexpected behavior at high voltages associated with significant heating of the storage layer. The boundaries deviate from the critical lines corresponding to the coercive field, which contrasts with the theoretically predicted behavior of a standard macrospin-based model. In this paper, we are proposing a modified model […]
Read moreA Route towards Dynamic Control of Skyrmion Chirality
The very popular magnetic bubbles called skyrmions are promising for dense data storage, logic and neuromorphic applications thanks to the unique sense of rotation (chirality) of their surrounding domain wall. The so-called Dzyaloshinskii−Moriya Interaction (DMI) is crucial for their stability. Here, T. Srivastava et al. have shown that DMI can be dynamically and locally controlled […]
