## Description

- description: "This paper reports a study of the low-temperature properties of 49-strand
    circular cables made of ultrafine National Institute for Materials Science MgB2
    wires. The critical currents of cables made from single-core MgB2 wires with diameters
    of 0.050 mm and 0.022 mm and different sheath materials (Cu, CuNi, and Monel)
    were measured at temperatures from 4.2 to 35 K and external fields from 0 to 8
    T. In addition, magnetization alternating current (AC) losses were measured at
    temperatures of 20–45 K, fields of 1–100 mT, and frequencies of 72 Hz and 144
    Hz. The presented experimental results show high engineering current densities
    in spite of a very low filament size of 8.5 µm and also low AC losses due to well
    decoupled strands. We show that the total AC losses are not only affected by the
    filament size but also by the sheath materials\r\n used. The cables presented
    here can possibly be used for small windings with low AC losses."
