Magnetic‐Field Tuning of the Spin Dynamics in the Quasi‐2D Van der Waals Antiferromagnet CuCrP2S6
Advanced Functional Materials, EarlyView.This study reveals 2D character of the spin dynamics in CuCrP2S6, as well as complex field dependence of collective excitations in the antiferromagnetically ordered state. Their remarkable tuning from the antiferromagnetic to the ferromagnetic type with magnetic field, together with the non‐degeneracy of the magnon gaps favorable for the induction of ...

An Algorithm of PWM Modulation under Low Switching Frequency
Kongzhi Yu Xinxi Jishu, 2013 The switching frequency of high power inverters is extreme low, so that the harmonic of PWM is very large. For solving the problem, a PWM modulation algorithm under low switching frequency was analyzed and studied, and the Matlab simulations and ...

Advanced Functional Materials, EarlyView.Thermal transport in Ru and W thin films is studied using steady‐state thermoreflectance, ultrafast pump–probe spectroscopy, infrared‐visible spectroscopy, and computations. Significant Lorenz number deviations reveal strong phonon contributions, reaching 45% in Ru and 62% in W.
