Insulator-to-metal transition in the pyrochlore iridates series (Eu_1-xBi_x)2Ir2O7 probed using Hard X-ray Photoemission Spectroscopy

Autor: Telang, Prachi, Mishra, Kshiti, Bag, Rabindranath, Gloskovskii, A., Matveyev, Yu., Singh, Surjeet

Eu2Ir2O7, a candidate Weyl semimetal, shows an insulator-to-metal transition as a function of Bi substitution at the Eu site. In this work, we investigate the (Eu_1-xBi_x)2Ir2O7 series via Hard X-ray Photoemission Spectroscopy (HAXPES), where substit

Breakthrough in HAXPES Performance Combining Full-Field k-Imaging with Time-of-Flight Recording

Autor: Medjanik, K., Babenkov, S. V., Chernov, S., Vasilyev, D., Elmers, H. J., Schoenhense, B., Schlueter, C., Gloskowskii, A., Matveyev, Yu., Drube, W., Schoenhense, G.

We established a new approach to hard-X-ray photoelectron spectroscopy (HAXPES). The instrumental key feature is an increase of the dimensionality of the recording scheme from 2D to 3D. A high-energy momentum microscope can detect electrons with init

An Approximate Backpropagation Learning Rule for Memristor Based Neural Networks Using Synaptic Plasticity

Autor: Negrov, D. V., Karandashev, I. M., Shakirov, V. V., Matveyev, Yu. A., Dunin-Barkowski, W. L., Zenkevich, A. V.

We describe an approximation to backpropagation algorithm for training deep neural networks, which is designed to work with synapses implemented with memristors. The key idea is to represent the values of both the input signal and the backpropagated

Grain-size dependent high-temperature ferromagnetism of polycrystalline MnxSi1-x (x~0.5) films

Autor: Nikolaev, S. N., Semisalova, A. S., Rylkov, V. V., Tugushev, V. V., Zenkevich, A. V., Vasiliev, A. L., Pashaev, E. M., Chernoglazov, K. Yu., Chesnokov, Yu. M., Likhachev, I. A., Perov, N. S., Matveyev, Yu. A., Novodvorskii, O. A., Kulatov, E. T., Bugaev, A. S., Wang, Y., Zhou, S.

We present the results of a comprehensive study of magnetic, magneto-transport and structural properties of nonstoichiometric MnxSi1-x (x=0.51-0.52) films grown by the Pulsed Laser Deposition (PLD) technique onto Al2O3(0001) single crystal substrates
