\mathcal is the only script font ‘built
in’. However, there are other useful calligraphic fonts included with
modern TeX distributions.
\mathcal.
Type 1 versions of the fonts are available in the AMS fonts
distribution.
\mathscr.
\DeclareMathAlphabet{\mathscr}{OT1}{pzc}{m}{it}
in your preamble. You may find the font rather too big; if so, you
can use a scaled version of it like this:
\DeclareFontFamily{OT1}{pzc}{}
\DeclareFontShape{OT1}{pzc}{m}{it}{<-> s * [0.900] pzcmi7t}{}
\DeclareMathAlphabet{\mathscr}{OT1}{pzc}{m}{it}
Adobe Zapf Chancery (which the above examples use) is distributed in
any but the most basic PostScript printers. A substantially identical
font (to the extent that the same metrics may be used) is
available from URW, called URW Chancery L: it is distributed
with Ghostscript, and as part of the “URW base35” bundle; the
urwchancal package (which includes virtual fonts to tweak
appearance) provides for its use as a calligraphic font.
