Are these anywhere in Logos?
I found one in NPNF but I'm looking for some where he explained the Trinity which don't seem to be there...
I don't think so. You can find The Letters of Saint Athanasius Concerning the Holy Spirit (these are the ones where he explained the Trinity) on the Internet Archive:

The "Read Online" version is very nice looking. The OCRed text version there is awful, though. Otherwise I'd maybe volunteer to turn this into a PB. It would be a ton of work to make it readable. And I'm in the middle of another even longer one right now which is higher priority for me.
Thanks Rosie, that gave me what I needed. [:)]
