I've seen some stuff in the 3.5 community that suggests if a spell is of the Conjuration type, has an instantaneous duration, and is of the Creation sub-school that the items created are not vulnerable to the effects of an anti-magic field.
I've read a few things that could support either side of the argument, but the most pervasive seems to be that the objects created by the spells in question are no longer considered magical, but rather are permanent objects, Thus the question:
Are Conjuration (Creation) spells with an instantaneous duration that create objects able to penetrate the effects of an Anti-magic field?
Addendum: And for Bonus points, if you're using the Psionics/Magic Transparency rules, does this also happen to apply to Metacreativity (Creation) Powers as well?

One, there is no such thing as an “antimagic barrier” – antimagic field does not block line of effect, it only suppresses magic inside of it. All magic can pass through an antimagic field to the opposite side of the field.1
The argument is that the effect of instantaneous Conjuration/Metacreativity (creation) spells/powers can exist inside the antimagic field. This is very well-supported by the rules, and rather difficult to argue against:
Antimagic field
Conjuration (Creation)
Metacreativity (Creation)
While neither antimagic field nor Conjuration/Metacreativity (creation) specifically calls out the other, the effect of antimagic field does not, to begin with, have anything to do with instantaneous Conjuration/Metacreativity (creation) effects, as the latter do not rely on magic for existence. Suppressing magic therefore does nothing to them, and they are not magical effects that would be suppressed. Furthermore, parallelism with the specific explanations of constructs and the undead indicates that this kind of distinction was very much intentional.
Therefore,
Yes, instantaneous Conjuration/Metacreativity (creation) effects can exist inside antimagic field
This still does not allow Conjuration/Metacreativity (creation) spells/powers to be cast/manifested inside the field, nor for the effect to be directly created inside the field; it only allows the effect, once created, to safely enter the field (e.g. when launched from outside as part of the spell, as with acid splash).
Whether or not there is transparency between magic and psionics has no effect on this ruling; if not transparent, antimagic field would not affect any psionic powers, and thus would still not affect Metacreativity (creation) powers.
