Figure 1. Temperature-dependent magnetization of TiAu.

(a) Left axis: zero-field-cooled magnetic susceptibility as a function of temperature for μ₀H=0.1 T applied field (1 e.m.u.=10 A cm⁻²). Right axis: inverse susceptibility H/M along with a Curie–Weiss-like fit (solid line), with θ≈−37 K (marked by a dashed line). (b) The crystal structure of TiAu with Ti (small) and Au (large) atoms, and the orthorhombic unit cell outlined in thin black lines. The arrows identify the crystallographic directions, marked by a, b and c axes.
