It would seem obvious that we cannot reproduce what you are seeing
without "Temp3" or bew2log" or "fitbew", but it also
seems as though
some of your questions are concerning how to mix text and Greek
letters in the ylab argument, for which the data is not really needed.
?plotmath
?bquote # I'm too clueless get either expression or as.expression to
"work".
# bquote also offers the possibility of substitution of values
through .()
jpeg(file="Tabh2.jpg",quality=100);
plot(1,1, xlab="log(T/K)", ylab=bquote(log(mu/cm^2/VS)), xlim=c(-4,4),
cex.axis=1, cex.lab=1)
legend(1.932,2.9,c("Experiment"),pch=1,bty="n")
legend(1.9,2.88,c("Regression","Theorie"),bty="n",lty=c(1,2));
dev.off()

You need bigger margins so the superscripted exponents do not get cut
off on the left side, not bigger plot regions, that is if you want
cex.lab > 1. To do that you need to reset the margins for the device
_after_ the device is opened.
jpeg(file="Tabh2.jpg",quality=100); par(mar=c(5, 5, 4, 2) + 0.1)
plot(1,1,xlab="log(T/K)",ylab=bquote(log(mu/cm^2/VS)), xlim=c(-4,4),
cex.axis=1.5, cex.lab=1.5)
legend(1.932,2.9,c("Experiment"),pch=1,bty="n")
legend(1.9,2.88,c("Regression","Theorie"),bty="n",lty=c(1,2));
dev.off()
I am on a Mac, so it is possible that you will not get the
satisfactory result I am viewing at the moment.
