A Neodymium magnet starts loosing its magnetic force at 80 degree C.

completely at 312 degree C; novak/feigao/lehner/wanderer/plettenberg/neu all use the Neodymium magnets.

Sintered magnets or segmented magnets are better suited for partial loads. this has something to do with eddy currents. the segments simple respond better to the signal than a larger lump. (it's like with transformers, the thinner the E's and I's are in the transformer, the higher frequency it is capable of handling. (the more efficient the transformer becomes at higher frequencies)

Might be true for one grade of Nd magnets, but there many different compositions and grades, optimized for different applications.
Our motors use what they call UHT (ultra high temp) grade Nd magnets, but even there you find differences.

And BTW, sintering is a way of manufacturing solid bodies. Basically it means "backing a powder together", or something like that.
