Graphical Abstract
  • superconductors have been analyzed. Clustering of the vortex system is demonstrated. The melting of a vortex lattice with increasing temperature has been studied. Keywords: high-temperature superconductor; HTSC; intertype superconductors; Monte Carlo method; vortex lattice; vortex–vortex interaction potential
  • interaction potential of which is identical in shape to the interaction potential in ferromagnetic superconductors. The modeling results can also be useful for analyzing vortex configurations in a layered anisotropic HTSC in an inclined magnetic field. Methods Calculations were performed using the Monte Carlo
  • method within the framework of a two-dimensional model of a layered HTSC [24][25][26]. Most of the HTSCs applicable in practice are strongly anisotropic substances characterized by the anisotropy parameter γ > 10. Examples of such HTSCs are YBa2Cu3O7−δ (γ ≈ 10) and Bi2Sr2CaCu2O8−δ (γ ≈ 200) [1]. Such

  • ; electromagnetic modeling; log-periodic antenna; RCSJ model; series Josephson junctions; YBaCuO Josephson junction; Introduction High-temperature superconducting (HTSC) Josephson junctions (JJs) have great potential as promising materials for creating high-frequency devices, such as microwave generators [1][2
  • Josephson detector was applied to detect a small signal from a BiSrCaCuO mesa structure at an operating temperature of 25 K [11]. A HTSC JJ has also analyzed pulsed terahertz radiation from quantum cascade lasers located in the same cryogenic environment at 50 K [12]. Another important advantage of HTSCs is
  • applications the performance of the HTSC devices is limited by the fairly low impedance of the JJ. It leads to moderate conversion efficiency in Josephson mixers [15][16] and reduced absorbed power in JJ detectors [17]. One possible way to solve this problem is to replace a single JJ by a chain or an array of

Graphical Abstract
  • ; Shapiro steps; temperature dependence; YBaCuO Josephson junction; Introduction High-temperature superconducting (HTSC) Josephson junctions (JJs) are of great interest since many physical properties can be observed in dynamics during the changing the temperature within a wide range from nitrogen
  • temperatures down to sub-kelvin, such as the phase diffusion regime [1][2][3], evidence for a minigap [4], and low-noise nano-junctions [5]. Such abilities raise not only fundamental interest in HTSC JJs but also an active search for ways to practically use such JJs. In recent years, the limiting
  • characteristics of detectors and mixers based on HTSC JJs [6][7][8][9][10][11] have been actively studied. Josephson junctions have also been used for various spectroscopic applications [12].
