Nanopoly — A FET-OPEN project

NANOPOLY proposes a ground-breaking yet cost effective method to extend our control over impedance and parasitic phenomena in monolithic circuit components by independently tuning electric permittivity and magnetic permeability of the integrated layers to values far beyond what nature can provide. This approach will re-define all components used in existing analogue circuit design regardless of […]

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 […]

Impact 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 […]

A 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 […]
