Question

The Fourier transform of a linear response function gives a “generalized” form of this quantity whose imaginary and real parts are related by the Kramers–Krönig relations. This quantity’s magnetic form can be measured with a torsional balance named for Evans. In ferromagnetic crystals, this quantity is a tensor of the partial derivatives of the i-th component of M with respect to the j-th component of H. The temperature dependence of this quantity above the Curie temperature is described by the (*) Curie-Weiss law. This quantity's “electric” form is the constant of proportionality between a material’s polarization and the external E-field, (-5[1])and equals the dielectric constant minus one. For 10 points, name this quantity symbolized chi (-5[1])that describes a material’s response to external electric (-5[1])or magnetic fields. ■END■ (0[7])

ANSWER: susceptibility [accept magnetic susceptibility or electric susceptibility; accept chi until read; accept volume, mass, molar, or differential susceptibility; accept generalized susceptibility or AC susceptibility; reject “x” or “chi-squared”]
