Weba form useful for shielding purposes and in any ~uantity was far from simple. Benaroya and Mogensen, 5 who undertook a study of the shielding properties of Nb3Sn with a view of making superconducting plate shields for a deflector system for a high-intensityvariable-energy cyclotron, give a good insight into the fabrication tech niques of the day. WebMar 20, 2024 · The Ferri. phase was the most dominant at a δ value of 0.267, showing an AFM phase of Fe at T < 20 K. Increasing the spontaneous magnetic moments reduced the magnetic shielding volume fraction due to the SC phase. This result was attributed to the magnetic phase of vanadium, which dominates the superconductivity of Fe in 21113V.
