Abstract: International audience; Future applications requiring high magnetic fields, such as the proposed Future Circular Collider, demand a substantially higher critical current density, $J_c$, at fields ≥16 T than is presently available in any commercial strand, so there is a strong effort to develop new routes to higher $J_c$ Nb$_3$Sn. As a consequence, evaluating the irreversibility field ($H_{irr}$) of any new conductor to ensure reliable performance at these higher magnetic fields becomes essential. To predict the irreversibility field for Nb$_3...
