Abstract Generation of second-harmonic waves is one of the universal nonlinear phenomena that have found numerous technical applications in many modern technologies, in particular, in photonics. This phenomenon also has great potential in the field o

Abstract Magnonic nano-devices exploit magnons - quanta of spin waves - to transmit and process information within a single integrated platform that has the potential to outperform traditional semiconductor-based electronics. The main missing corners

Abstract Nonlinear self-phase modulation is a universal phenomenon responsible, for example, for the formation of propagating dynamic solitons. It has been reported for waves of different physical nature. However its direct experimental observation f

A gas of magnons, quantised magnetic excitations, can be driven into a Bose-Einstein condensation (BEC) state even at room temperature. Here, Divinskiy et al show that it is possible to achieve stationary equilibrium room-temperature magnon BEC via a

The Aldegonda (Aldegondabreen) Glacier, located on the Nordenskjold Land, West Spitsbergen, covers the area of about 6 km2 (in 2018) and does constantly retreat since the very first observations of 1936. In August 2018, a topographic survey of the gl

Little is known about the underlying mechanism responsible for the spatial stability of magnon Bose-Einstein condensates. Here experimental evidence is provided for a repulsive interaction of magnons in the condensate resulting in its stabilization.

Spin current-induced quasi-equilibrium state of magnon gas described by the Bose–Einstein statistics has been previously theoretically predicted. Here, authors experimentally show that the spin current-driven magnon distribution can be treated ther

Spin-orbit interactions allow for pure spin current to be injected into a ferromagnetic insulator from a current-carrying heavy metal, generating torque on the magnetization. Here, the authors evidence magnetic auto-oscillations driven by spin-orbit

Previously published geodetic mass balance data indicate glacier shrinkage in the Barentsburg area of Svalbard since the beginning of the 20th century on the decadal time scale. However, observations for shorter time spans allowing one to compute the
