Can Neo be magnetized easier by raising the temperature during magnetization?

RE: NdFeB magnetizing
Sounds like you just need more power.
One thing to check with pulse magnetization is the pulse duration.
It is often better to slightly reduce the peak field in exchange for longer duration.

P.E. Metallurgy, consulting work welcomed
RE: NdFeB magnetizing
In addition, you run the risk of the magnet self demagnetizing a bit because the heat reduced the coercivity too much.
The IEC published a nice technical report in 2009 on the magnetization behavior of permanent magnets. Amongst other things it showed, in general, that 3 Tesla is adequate to magnetize Neo.
Here's a link to the IEC Webstore for that technical report:
