Finally, the Heaviside step function [THETA](t - t') in (1) reflects causality and ensures that the spin density at time t is only influenced by the magnetic field at times t' < t, if the dynamic spin susceptibility is interpreted as the linear spin-density response function by means of Kubo's formula.

initially predicted FM with a high Curie temperature ([T.sub.c]) in p-type Mn-doped ZnO via local spin density approximation [7, 8] while simulations by Sato and Katayama-Yoshida predicted FM in V-, Cr-, Fe-, Co-, and Ni-doped ZnO, but suggested that Mn doping by itself may not be sufficient to induce FM [9], a conjecture that has been supported by local spin density approximation [ 10], B3LYP hybrid density functional method [11], and gradient corrected functional density theory [12].

The quality of the MRI images depends on three NMR main parameters (the proton spin density, the nuclear spin-lattice relaxation time T1, and the spin-spin relaxation time T2), and the contrast agents (CAs), based on the different distribution of nuclear-spin density along the body, are able to improve the image contrast by increasing (locally) the nuclear relaxation rates [2].
